I'm running a mail server for our small non-profit business. Recently the powers that be decided they wanted to use Outlook for its schedule/calendar capabilities. So I went with Kerio on a Core4 box. We are also running VoIP, and with the extra traffic generated by IMAP, our phone calls were suffering. Rather than spend quite a bit of money (which we don't have) to increase our bandwidth to central location and 7 remote sites, I decided to dual home the Core4 box, then route the IMAP traffic through the VPN tunnels using QOS on VoIP routers to control traffic flow. So I added second NIC and gave it a static IP on the LAN. That works fine, but as soon as I activate the second NIC, the public NIC with FQDN stops responding. I can ping it from our LAN, but not outside the LAN. If I remember correctly, RH9 performed dual home with no additional routing or anything else. Please, what do I need to do to get Core 4 listen/respond to both NICs?

Thanks much.
