I am currently running 2.0.2-RELEASE (i386)/FreeBSD 8.1-RELEASE-p13 and am having an issue at the moment using multiple wan connections in a gateway group. We have three ADSL connections running on the site connect to WAN, OPT1 and OPT2 addressed as follows
WAN -> 18.104.22.168 Gateway (WANGW) 192.168.22.1
OPT1 -> 192.168.21.250 Gateway (OPT1GW) 192.168.21.1
OPT2 -> 192.168.20.250 Gateway (OPT2GW) 192.168.20.1
LAN Subnet 192.168.24.0
LAN interface 192.168.24.1
Our gateway group is called mulitwan and has all three WAN connections in it as tier1 connections (round robin).
Currently if we configure the LAN firewall rule to use the mulitwan gateway group as its gateway none of the machines on the LAN can browse websites (Secure and Nonsecure). However if I set the gateway to be our WANGW then there is no issue.
If I revert the gateway back to our gateway group and use something like bitorrent then I can see traffic going out all interfaces. I can also see SIP and DNS traffic successfully going out using the gateway group. However as soon as we revert to the gateway group then we will lose the ability to browse the internet on machines behind the firewall.
I have tried adding floating rules, ameding DHCP to pass google DNS servers to clients just in case it was a DNS thing all to no avail. All gateways are showing as up as per status > gateways and I can ping a host on the internet from each wan interface using diagnostics > ping
We had been following http://doc.pfsense.org/index.php/Multi-WAN_2.0
as our initial guide on configuration. I was hoping someone might have a pointer as to where I could go next
