We have 4 WAN Connections connected to a TL-R480T. ---- The LAN is connected to a CISCO ASA 5510.
so the connection between internal network and internet is the CiscoASA 5510.
The problem: All printers are set up to use Scan-to-Email feature which they need to have access to the SMTP Server, but sometime they work sometimes they have to try 5-6 times to get it work. obviously its because of the Multiple WAN Connection and SMTP server is only reachable from WAN 1. So whenever they have problem, the packet is going to the wrong WAN.
So All i need is to tell the Cisco router: SEND ALL SMTP TRAFFIC to 192.168.x.x which is WAN1.
Im not sure how to do this. Should i do this? Help please.
there are 400 users using these printers and Im in charge! imagine the pressure!
