Multi wan - gateway offline
-
Ok , The only thing I see that is missing is your DNS failover. You should have a rule on the floating tab, with both WAN interfaces set to DNS port I will include a screenshot of my rule.. You will also need to then go to your general settings and set the DNS to none. I will show you in the shots.
also could you include one of the Gateway Group? Are both gateways set to Tier 1 ?
I know in the lab I have failed over static gateways with no issues. It's static , Once it comes back online the interface should come up and new traffic should start getting routed via that gateway also.
When you say , Physically disconnect WAN2 , let it failover to WAN1. Wait 5 minutes , Don't clear any states just let the TTL's expire in ARP table..ect..
Now , Re-Connect WAN2 , Check PFsense to see if the gateway goes ONLINE. If the gateway goes online..
Go to a host, Go to say.. www.dnsleak.com and Refresh until you get both your IP's to show. ( If you refresh 40 times and nothing happens…then..)
Now the issue that Tim talks about I am not sure and unable to confirm right now , I have a lab I can try today with 2 cable modems running on different gateways with a DHCP lease. I will let you know my findings.

i have made the dns rule but no difference at all and for the DNS gateway , i don't have the gateway tab in my pfsense beside DNS servers
but i have noticed that from seeing the next hope after the pfsense which is a cisco router
after i bring back the second line online no packets hits this line at all
and all the traffic goes to the first line , and all the icmp used in monitoring is generated from one interface
is that normal . after one line goes down all the icmp traffic used in monitoring goes to one line
so how it could check if the second line is come back online ??notes: the dsl lines are not directly attached to pfsense , and their is a cisco router after the pfsense and after it the 2 dsl lines
so why the pfsense is insisting that the wan is offline and it didn't came back online
-
i figure out that it comes back online but after a few hours
-
Does it come back online if you renew the interface ? or disable and then re-enable it?
-
it comes back if i enter to the wan interface (the down one) and i just click save and apply changes without made any configuration.

Post a screenshot of your gateways and gateway groups.. are both tier 1?
-
YES , tier 1

Your WAN is on 10.24.250.x Net & your WAN2 is on 10.24.250.x Net also, are you sure that both Netwworks doesn't overlap ? Which network mask do you have on each WAN ?
Maybe you need to elaborate a bit more about your setup…

Internal NIC on 10.24.250.x as well. Unless those are small subnet masks, all 3 NICs may have overlapping subnets.

it's all /29 subnet mask

i have another problem now that i found that squid proxy is not working with multi wan when i enable it and i enable proxy on lan and loopback interfaces :(
-
I have the same problem with multi-WAN switching. Please help.
-
Same problem here.
My ISP disconnects every 24 hours automatically. So WAN1 goes offline, comes back after a few seconds, but PfSense is still saying 'Offline'. I've set the monitor IP to an IP which is definitely pingable.But I have to say I'm using PfSense 2.1-BETA1 (March 28).
Any ideas to solve this??

Have same problem here.
When I dissable Gateway Monitoring it works.I have tried a high down ping time, ms and packetloss but with same problem.
I am running 2.0.3
