I have two locations each using OpenBSD 4.5 for their gateways with the two subnets connected using IPSEC.
I have an application that requires IPX/SPX between the two locations. Is this feasible? The two internal subnets are 192.168.0.x and 192.168.1.x but they can easily be changed. enabling IPX in the kernel? PPTP from each workstation to the XP server? bridging the two networks? I don't know much about IPX/SPX and what it can or can't do between the two locations.
