[Solved] Multi WAN not working in new DMZ interface.

[bobbythomas]

Hi,

I have recently configured a new DMZ interface to host my BitTorrent client. Previously this was on my inside network and Multi WAN loadbalancing was working without any issues, but since I moved it to DMZ multi WAN load balancing is not working. When my primary link goes down it loses internet connectivity, while I have internet access on the LAN interface through secondary link. I am able to ping the gateway and monitoring IP from the DMZ host when the primary link is down and it's able to resolve DNS, but whenever I try to ping any other host I am getting destination host unreachable from the firewall DMZ interface.

Any solution?

Thank you,
Regards,
Bobby Thomas

You added the multiwan FW rules also to the DMZ tab?

[bobbythomas]

Actually I have added block rules to all internal networks and allow rules to all other network including public network. Is there any specific firewall rule I need to add?

Thank you,

The allow rules needs the gateway group set.

I don't see an option to set the gateway group in the rule config.
