Cannot receive external email - 21.Aug.2009 11:58:44 AM

SBS 2003 Standard configuration: ATT ISP w/Netopia 3347-02 (PPoe with Subnet Routing) ---> Firewall (Router Mode) ---> Network Switch --->ESVA (Email Security Virtual Appliance w/Postfix @192.168.xx.200)--->MS Exchange 2003 (SBS 2003 Standard @ 192.168.xx.1). The firewall Port 25 is forwarded to ESVA 192.168.xx.200. Firewall scans and sends email to ESVA who scans again and delivers to Exchange. Works flawless. All company outbound email is sent by Exchange. Works flawless.

The ESVA (192.168.xx.200) box required maintenance, shut it down and routed firewall Port 25 to Exchange. All inbound email was being dropped by Exchange.

I can telnet both the ESVA and Exchange boxes from inside the LAN from a workstation and from the firewall box. From the Internet I can telnet to ESVA, but if I switch the firewall to point to Exchange (192.168.xx.1) I cannot telnet to it. No 220 response just a blinking cursor. I pulled out the firewall and put in a Netgear WGR614 router and got the same results.

This configuration worked with One Communications, one static IP and a bridged modem. Netopia and sticky IPs, PPoe using routed subnet appear bothersome. Any ideas would be appreciated.
