I have a scenario where I have a PBX (10.0.0.xxx) on the Lan of the router.
Wan 1 has an internal address of my customers network 192.168.1.xxx and is connected to his switch, his mail server is on this local network @ (192.168.1.2).
Wan 2 has a public IP in it and is connected to a DSL modem.
All I want to do is from my PBX (10.0.0.xxx) send all the SMTP traffic port 25 directly out Wan 1 and to his mail server.
Everything else I want to go out WAN 2 to the internet (SIP Trunks etc.)
Linksys said I need a router that does Protocol BInding which the RV042 does not do and cannot achieve.
Any preference/recommendation between the RV016 or the SA520 Cisco? Both are Dual WAN. Do both do protocol binding or a form of it that will work?
Sombody must have experience with both and can give me a recommendation.
