I'm running Merlin 376.49_4. My intention was to use the Dual WAN feature as I live in a remote area in Canada, with two WISP connections (one my own (20-30 Mbps), the other a commercial provider (max 4 Mbps)). As the commercial provider is considerably slower, I wanted them as my failover backup.
I set up the Dual WAN feature after playing around with the router, and set the Failover on, using Ethernet LAN and directing it to Port 4. After pulling the WAN connection, the router failed over OK, but did not get a two-way connection. My commercial provider said he could see my internal IPs, so my Port 4 was still (presumably) acting as a LAN port and not on a separate VLAN acting as an internet port.
After a LOT of reading and trial and error, I ssh'd to the router, erased nvram and reset up the router. The failover still worked and I got "some" outside connectivity BUT:
1. The WAN address when I went to Network Map kept flipping between 10.100.103.xxx (the commercial provider's internal static address for me) and 0.0.0.0, along with netmask and gateway. DNS stayed static. During this time internet connectivity was....poor, lots of dropped packets etc. The "flip" happened every 15-30 sec or so.
2. The failback was set: this caused repeated attempts to reconnect to the Main WAN (likely b/c the backup WAN was so crappy?).
3. Even after nuking the failback and the ping watchdog, much of the same behaviour occurred. Very poor connection, lots of packet loss.
I did confirm via ssh'ing to the router (which I really know nothing about!), that ports 1,2,3 and 8 were on one VLAN and ports 4 and 8 were on another (VLAN 3 IIRC).
Has anyone managed to get this working and, if so, how? I've seen a few threads here that indicate that it does, indeed work (without failback which I'm fine with - I can do that manually), but no real indication of how, especially when using the LAN port.
(Hopefully this makes sense! I'm adventurous, but a networking guru? Heck - no one would ever accuse me of that!!)
Love the forum - clearly there are a LOT of smart people here!
