How to disable loadbalancing and use failover on dual wan config?

All my thanks go to Hobo!!!

You are the man!!!!

That was the SMC 8014 Cable Modem - Comcast businesses gateway problem!!!!

I disable DHCP, firewall, restarted the router couple of time since it was not renewing IP. And it worked like a charm!!!!!

Thank you!!!! Thank you!!! Thank you!!!!!

Sorry to hijack your post V-man but I’m trying to implement the very same thing as you “failover with no load-balance” but I’m not getting as far as you and wonder if one of you could give me some pointers.

My config:
Pfsense = v1.2
WAN 20MB = 82.29.156.0/22 SM = 255.255.252.0 GW = 82.29.156.1
Backup (OPT1) 2MB = 82.29.148.0/22 SM = 255.255.252.0 GW = 82.29.148.1
LAN = 192.168.100.0/24 SM = 255.255.255.0 GW = 192.168.100.254
Wireless = 192.168.101.0/24 SM = 255.255.255.0 GW = 192.168.101.254

I too have read the http://doc.pfsense.org/index.php/MultiWanVersion1.2 document but got compleetly confused at the sticky connections as my understanding is that I don’t want any so that if my wan connection fails my mail server’s mail's will be re-routed out the fall back gateway.

So with this in mind I tried to set up a lab environment on some spare hardware dropping the load balance rule from the pools and keeping WAN1->WAN2 and WAN2->WAN1 filters. This is where I got stuck, no matter what I do I cannot get it to fail over to Backup (OPT1) but the fact that others can and the fact that I’m not exactly thick means I must be missing something obvious. I think I’m just getting confused with the terminologies used in PFSENSE when I’m comparing it to other distributions I have used.

Any help you guys can give would be great

Did you set the gateway(s) of your LAN rule(s) to the failover pools?

At the moment I have a basic config with no pools setup.
I am driving remotely over VPN so don't want to get locked out.
This is what I have atm,

I did have mail -> out 'locked' to backup (OPT1) link but understand that when that link fails it needs to use the WAN link.

Reading another post,
http://forum.pfsense.org/index.php/topic,8994.0.html,

You said one can simply add more lines to the load-balance filter to balance out the faster modem! So could I not just have one load balance line,

2 lines with 2Mbit and 20Mbit
line1: 1 times in list
line2: 10 times in list

What happens in this scenario when one line goes down does it simply round robin on to the next working one or does it time out?

I just want some advice from you guy's on how you would best 'tweak' my config to get the most out of it with the most important thing being remote connectivity in the event of the WAN failing.

Cheers

Hi there,

Right I have read your question a couple of times and I now see (with your help) where I went wrong.

For some reason web browsing works fine with either wan disconnected but I can only ping Google with WAN connected and I get a timeout using only the Backup, strange!

Also I still don’t understand how the three load balance rules work, If I have a dead link in all three rules how does it know which one to use?

I will play some more while I'm feeling brave.

Cheers for your help
