Two Netgear WNDR3700’s are now running here at twibble.org and both are loaded with locally built versions of openwrt.
The first is running as a router, switch, 2,4GHz access point, 5GHz wireless client. dhcp server and radvd server, while the second is running as a 5GHz access point, firewall (shorewall), vpn server (openswan), 6to4 gateway, pppoe client and router.
The 5GHz wireless bridge link carries multiple subnets and IPv6 and IPv4 traffic without any issues, unlike the bridge devices it replaced which could only handle single subnets and no IPv6. Previously a GRE tunnel was used over the link to allow them to be used here.
