Im back again!! I have a Dual WAN Netgear prosafe FVS336G firewall with one ISP on WAN1. The organization has another ISP (Comcast) sitting aside doing nothing. I'm thinking about connecting this second ISP to the WAN2 on the firewall. The modem from comcast is a Business IP Gateway Modem with a dynamic IP. Now, my questions are..... will be easy to set up this second ISP on the firewall. Will it mess up the ISP on WAN1? does it matter that the comcast modem has a dynamic IP? Will this second connection mess up my email server when sending or receiving emails? I just want to make sure I do it right! Do you have any idea of how to set up the Dual WAN firewall with Business IP Gateway with a dynamic IP from Comcast?
