Advantech is keeping quaterly FW release schedule, let's look at some noteworthy changes and additions. Full description can be found in Release Notes.
Added ebtables program, which can be used as an administration tool for firewall IP packets filtering. It enables transparent filtering of network traffic passing through a Linux bridge. The filtering possibilities are limited to link layer filtering and some basic filtering on higher network layers.
The ebtables tool can be combined with the other filtering tools (iptables and ip6tables) to make a bridging firewall that is also capable of filtering these higher network layers. Check the Commands and Scripts application note for more information about this program.
Added DHCP Authoritative Mode
Configuration of the DHCP server, running on our routers, was updated to act as the authoritative DHCP server for all WiFi clients. Authoritative DHCP server is a server which always responds to a DHCP request if no another DHCP server in the network responds. This configuration prevents issue with obtaining the IP address for some WiFi clients having a valid address assigned in another WiFi network.
Fixed WiFi Issue (ICR-32xx)
Fix for transmit issues on the Laird SU60 WiFi module. This issue caused the WiFi to stop working. If required, this fix will invoke reboot of the router.
Fixed OpenVPN Issue
