SG-3100 + Netgear LB2120 observations



  • I was able to setup WAN failover using the LB2102 on the OPT1 port very easily. The key is using it in bridge mode.

    However I was only ale to get it working using the OPT1 i/f and not use the native LB2120's pass-thru wireline mode with IPv6. "In theory" it should just work in bridge mode if the wireline WAN is up.

    The SG-3100 got the DHCP6 config correctly but the LB2120 would not pass IPv6 traffic. IPv4 was working fine in wireline and 3G/4G failover.

    So far I can get the OPT1 config working only in IPv4 mode.

    The APN config is set for both IPv4+IPv6 it's just not moving the IPv6 traffic after the DHCP6 client gets the addresses.

    The current LB2120 details:
