Okay I think I lost you guys. Tim says I can't assign separate gateway IPs for each ISP, which based on my goal of replicating my current setup will then mean I can't proceed unless I go the route of similar multi-wan setups using PFSense. Which isn't something I'm prepared to do. Yes, I'm a little stubborn. :)
However, if what Frank is saying is true, then how do I proceed with that? I think if I can get that started, I can start applying what I have read so far along with the help Tim has earlier provided.
Backup scenario I'm thinking of for my setup is running a VM Server with 3 DDWRT appliances. Yes, it's dirty. That's why I'm trying to get with the times and learn PFSense. I'm hopeful it could be done.
