We have two FreeBSD 2.2.1 boxes, "hoth" (at a branch office) and "andrew" (at head office). Andrew has a Real Connection to the internet, and hoth doesn't, so they are connected with a dial-on-demand PPP modem link. The catch is that head office is on a different network to the branch office, and we cannot change the routers which feed head office, so we are using NAT (via the -alias option in user mode ppp) at hoth. We have a static route to the branch office IP range set up on andrew. This works for connections from hoth to andrew, but for some reason we can't get connections going the other way. To be more specific, we can ping any host on the branch office network from andrew, but we can't telnet or make any other connection. Is this a restriction of NAT or it's implementation? Or do we just have something misconfigured somewhere? Thanks for your time. -------------------------------------------------------------------------- Alastair Rankine Ph: +61 2 9459 2500 Whitesmiths, Australia Pty Ltd Fax: +61 2 9957 4369 Level 1, Suite 108 email: rankinea@mail.ns.wsa.com.au 40 Miller St., North Sydney New South Wales, Australia 2060 --------------------------------------------------------------------------
