How do you route across a Snow Leopard server?
I think it's a routing problem…
I'm replacing a Linux server with a Snow Leopard 10.6.2 server. The Linux server is a one-machine firewall/router/nat/vpn/dhcp/ftp/web/mail/file-server. All traffic between the internet and internal LAN pass through it.
My goal is to migrate all Linux services to the SLS and kill power on the Linux box. That process has hit a bump with routing through the SLS.
Internet clients connect to the SLS VPN and can access all IP addresses/services on the internal, 192.168 network -- except the SLS internal 192.168 IP address. When I configure internal clients and servers to use the SLS 192.168 IP as their default gateway, they cannot see (ping or otherwise) the internet facing IP address on the SLS. They can access the internet through that interface, though.
The firewall on the SLS accepts any packet on the 192 network and limits internet traffic to only hosted services (pretty much the default firewall configuration). The NAT service is configured for IP forwarding and NAT.
Is other configuration need so that the SLS routes packets from one of its interfaces to the other?
