Hopefully I can get some help or pointers here.

Have a multiwan gateway which is moving home. It had 3 WAN and 1 LAN, 1 Wan now inactive(eth2), 2nd LAN is dedicated fibre (eth4), 3rd WAN is standard broadband link (eth0)

- We disconnected the 3rd WAN today and 4/5 of 20 users dropped out of AWS, some could resolve to internet DNS though and also to Firewall GW address
- WAN 2 is being dropped and will be replaced by another link. But for now 3rd WAN will be the primary link.
- We are pretty sure that when system relocates and plugs back in that those 4/5 users will connect and the rest wont!

Questions are how easy it to disable the WAN link -eth0(2) as it is being left behind, disable/delete or just leave as link down
Also how do we get all lan clients to use WAN3 eth0 as the default route out.
We can see weightings on the Eth ports, WAN2 is set to primary with w=10
WAN3 is set to primary also with w=1

Both eth0 and eth4 have dest port rules set for 80 and 443

Thanks

Jamie

    Hi Jamie,
    I've just bumped into this old post and noticed you'd not had a reply.

    Can I suggest that when you drop a WAN connection, you change it to LAN so MultiWAN does not keep trying to use it? I'd avoid deleting the NIC as I don't think there is an easy way to re-add it.

    Another thing with MultiWAN if they are through different ISP's is that you use a public DNS service such as OpenDNS or GoogleDNS (there are others) rather than your ISP's DNS servers. I would also use ClearOS as the DNS server for the LAN and configure the DHCP server like that, although it could also be configured to hand out pblic DNS server IP addresses.
