Ubiquiti EdgeRouter ERLite-3 Router Firmware 1.8.5 Description

New features:

Offload
- Add "Hardware NAT" offload function for the ER-X platform (i.e., ER-X, ER-X-SFP, and EP-R6 models), which can significantly improve packet forwarding performance while reducing CPU utilization. Currently this supports IPv4 and IPv6 traffic including VLAN, PPPoE, bridging, etc. Currently this is disabled by default and can be enabled by: set system offload hwnat enable

Switch
- Add "per-port VLAN" feature for the ER-X platform. Now "untagged" and "tagged" VLANs can be set for each port in "switch mode" on the ER-X platform (including ER-X, ER-X-SFP, and EP-R6).
- This would set VLAN 100 to be "untagged" on port eth3, and VLANs 200 and 300 are "tagged" on port eth3. Note that the global "vlan-aware" setting (default disabled) enables the new "per-port VLAN" feature. If this is not enabled the swith ports will function the same way as before, i.e., simple L2 switching with no per-port VLAN and will pass all VLANs automatically. Also none of the per-port VLAN settings will have any effect if vlan-aware is not enabled.

DPI/Traffic Analysis
- Add DPI and Traffic Analysis features for the ER-X platform (including ER-X, ER-X-SFP, and EP-R6 models). This means all current models now have support for DPI/Traffic Analysis. The features function as with the other platforms, and it is disabled by default as well and can be enabled from the Web UI Traffic Analysis page or using the CLI: set system traffic-analysis export enable or set system traffic-analysis dpi enable

A few things to note:
- If the new "HW NAT" offload feature for ER-X is also enabled, traffic to which HW NAT is applied is handled by the hardware directly and therefore Traffic Analysis/DPI cannot see such traffic.
- Also, similar to the offload features for the older platforms, certain traffic is not eligible for offload, e.g., traffic that requires QoS policy cannot be offloaded.
- This means that on the ER-X platform when both Traffic Analysis/DPI and HW NAT offload are enabled, it is possible for some traffic to be seen in Traffic Analysis/DPI but not others, e.g., traffic requiring QoS cannot be offloaded and therefore can be seen by Traffic Analysis/DPI.

Enhancements and bug fixes:

- [IPsec] Change implementation of "initiate" connection type as the original implementation does not work well with the newer version of strongSwan. More specifically, it now uses "auto=route" instead of "auto=start" (which is not recommended by strongSwan as it could be broken in cases).
- [IPsec] Change the VTI interface handling logic so that the link up/down is no longer tied to the IPsec status. (Note that this is not the same as changing the script to not "down" the interface which was discussed previously, since that would still tie the link "up" to the IPsec status.)
- [IPsec] Make "ipsec-interfaces" setting deprecated (it is not actually used for the strongSwan config and also causes warning with the new version of strongSwan).
- [IPsec] Add validation for aggressive mode to disallow its use with PSK (since it is not allowed by strongSwan by default).
- [IPsec] Add validation for RSA authentication to disallow its use if peer is 0.0.0.0 (any).
- [IPsec] Add more crypto options for ESP group configuration, including "aes128gcm128" and "aes256gcm128" for "encryption" and "sha256", "sha384", and "sha512" for "hash".
- [IPsec] Fix packaging for strongSwan packages to include the "pki" tool.
- [IPsec] Change log level for IPsec offload log messages that are not useful in most cases. - [Offload] Fix possible "download corruption" issue triggered by packet corruption that happened upstream (before reaching the router).
- [DNS forwarding] Update the underlying dnsmasq software to the current version 2.75, now building/packaging it ourselves. The new version includes quite a few new features, which are not yet explicitly supported in the router configuration but can be used with the free-form "options" config setting for DNS forwarding for example.
- [System] Update iproute2 to version 4.4.0 for enhancements/fixes (e.g., ip6gre tunnel, possible fix for segfault, etc.).
- [System] Change upgrade code to delete old version first if if there is not enough space for the upgrade operation. For CLI upgrade this will ask the user for confirmation, and it's automatic when doing upgrade through the Web UI. In particular, this is useful for the ER-X platform which has more limited storage and may often require it. (Of course the new upgrade code will only take effect at the next upgrade.)
- [System] Only load MPLS forwarding module when MPLS-related features are configured. This avoids the performance overhead from the module when MPLS is not configured.
- [System] Update copyright date in Web UI and CLI.
- [System] Adjust sudo logging level to avoid spamming syslog with successful messages at default syslog level.
- [System] Apply appropriate permissions and cleanup to temporary file created by commit-revisions feature.
- [System] Fix long boot time in some cases when DNS server is not reachable, which may also cause other config issues.
- [System] Add support for new SSH key types for user public key and the "loadkey" command.
- [System] Fix local IP address check for IPv6 addresses.
- [System] Fix typo in the "vyatta-bridge.pl" script.
- [Web UI] Update to PHP version 7 with the required cross-build changes and fixes.
- [Web UI] Remove support for legacy browsers, and "native WebSocket" support is now required, for example the following browsers are supported: Any recent versions of FireFox, Any recent versions of Chrome, IE 10 or higher, Edge, Safari 7 or higher.
- [Web UI] Add support for using only newer (stronger) ciphers for HTTPS. Note that older ciphers are required for wider browser compatibility, but if that is not a concern, they can be disabled by: set service gui older-ciphers disable
- [Web UI] Add new config setting for the "HTTP port" of the Web server, for example: set service gui http-port 8080
- [Web UI] Implement proper HTTP-to-HTTPS redirect in the case of non-default HTTP and HTTPS ports. Previously the code always used port 443 for HTTPS and therefore the redirect breaks if non-default HTTPS port is used.
- [Web UI] Add new config settings for Web server certificate files. For example, to specify a particular server certificate (including private key): set service gui cert-file /config/auth/server.pem
- [Web UI] Fix sorting issue on the Traffic Analysis page for entries with "Tbytes" unit.
- [Web UI] Add the "VPN Status" feature wizard.

- [Web UI] Fix firewal rule validation for protocol.
- [Web UI] Add support for TCP reject action for firewall rules
- [Web UI] Change firewall rule reordering so that rule numbers are incremented by 10 (i.e., 10, 20, 30, ...) after reordering.
- [Web UI] Fix branch node creation for Advanced Queue.
- [Traffic Analysis] Improve handling of "external IPs" to reduce less useful entries occupying Traffic Analysis data (however this may not eliminate all cases of "external IP" entries).
- [Traffic Analysis/DPI] Improve handling of flow stats in some cases.
- [DPI] Add built-in categories including "Web".
- [DPI] Add validation to disallow DPI application matching in firewall and advanced queue on platforms that do not support DPI yet.

- [Interface] Enable Ethernet flow control (pause frames) auto-negotiation by default on all interfaces of all models (except the "combo" ports on the ER Pro). Note that it still requires auto-negotiation and so pause frames will only be used if the other side also supports and advertises pause frames.
- [Interface] Fix kernel setting for eth5 (SFP port) on the ER-X-SFP and EP-R6.
- [Interface] Fix some auto-negotiation/speed issues for the SFP port on ER-X-SFP.

- [PPPoE client] Fix interface rename when IPv6 is configured on the PPPoE interface.
- [QoS] Remove the "set-dscp" setting from traffic-policy as it does not work "correctly" and causes issues. In most cases, setting DSCP can already be done using "firewall modify" rules instead (which also allows more flexible matching criteria etc.).
- [Dynamic DNS] Add No-IP service as an explicit option for DDNS configuration both in CLI and Web UI.
- [L2TP/IPsec] Update config validation so that it no longer requires deprecated IPsec settings (interface and NAT traversal settings).
- [PPTP server] Fix typo in config help text.
- [MPLS] Change "propagate-ttl" to disabled by default, which is consistent with the default config.

About Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn’t either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn’t be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don’t always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you’re looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don’t power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don’t miss the update that will improve your device. 

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
