I wondering if anyone has run into a situation such as this.
I have two WAN connections one is a Comcast Cable modem connection (currently being used with the PIX without issue) and a T1 that I have just had installed. Currently my email is routed over the comcast connection works great. What I would like to do is this. I have a failover PIX and would like to use both Pixs with both WAN connections. Both Pix's already have a second network card.
I would like my client traffic to over the Comcast circuit and the server based traffic over the T1. But I'd like to Pix to accept inbound SMTP from a secondary MX record on the comcast if the T1 is down. Also would like to failover to the circuit that is up if one is down. I don't believe I can do this with the PIX but I do have access to multiple Cisco routers.
Anyone have any ideas?
