Multi WAN Routing



  • Hello Everyone,

    I'm trying to figure out how to route between my wan interfaces.

    WAN2 Virtual IP –> WAN1 Public IP

    My goal is to take some of the traffic off of WAN1(ISP1) and route it through WAN2(ISP2) without changing any IP addresses.  I have both WAN's setup and working great.

    Any help would be appreciated.

    Thanks



  • You can't do that without changing IPs, short of having your own AS and PI IP space which is not doable unless you're big and have a big budget, or are an ISP with hundreds of customers minimum.



  • My company leases both subnets and uses them as they see fit.  I don't see why I can't route one ip(ISP1) to another(ISP2).  Maybe it is just that pfsense can't do it?



  • Are you talking about local routing, i.e. getting from WAN2 to WAN1, or actually routing traffic on WAN1's IPs out WAN2 (or vice versa)? The latter is what I thought you were referring to. The former requires NAT reflection to be enabled if you're using NAT.



  • Yes, that is exactly what I want to do.  I want to route a WAN2 ip through pfsense to a WAN1 ip.



  • Just enable NAT reflection. Cleaner to use split DNS but reflection will work.



  • Can't seem to get the 1:1 NAT to work.  I'm using the latest version of pfsense.  I have a virtual IP on OPT1 that I want to route to a WAN IP.  I've setup the 1:1 with rules, but no luck.  Any advice would be helpful.  Thanks.



  • I was able to get the 1:1 NAT working from the LAN, but I'm still having problems accessing the NAT from the outside.  I did notice that the connection is very slow from the LAN.  I just want to map one IP from OPT1 to an IP on WAN.  What am I overlooking?
