Hm -- how about using proxy-arp style routing? If their router has has proxy-arp support turned on, then you can set yourself (ie your own IP) as the default and will arp for _all_ addreeses of _all_ remote boxes you try to connect to. Then their router sends a response to the arp-request and your box gets an apr table entry of the router (within the local ethernet-broacast realm) and will send stuff for whatever remote IP address you have. It's not the cleanest solution, but I've used it under windows, linux and hpux to get around the foolishness of a network architecture I couldn't change... I used this at an old job where I had non-contiguous IP networks in the same ethernet-broacast domain so that all the machines would find each other on the local network, and the router handled all the off-segment connections via proxy-arp. I have NOT tried this under FreeBSD as I thankfully dont work there any more (was converted to the FreeBSD religion after I left...). Alternatively, you could use an exceptionally permissive netmask so that the local box _thought_ the other IP was in the same 'network' as yours. Pretty much both achieve the same effect of putting the remote router on the 'same network' as you. Good luck.
