what is "it"? Both of what? Network administration can be quite complicated and is beyond the scope of this *mailing list*. From what I remember from this poor imitation of a mail thread (I know why I hate Backup Central), I'm not surprised. It's perfectly possible (though usually not sensible) to masquerade outgoing connections (as seen by the VPN endpoint) from a routeable IP while passing through incoming connections unaltered. In a Linux firewall, you'd have to -m state --state NEW in the SNAT rule in order to match outgoing traffic but not the return packets for incoming traffic (though when I think about it, I think that's implicit, i.e. the nat table is only considered for new connections anyway). I can't tell you how to switch off masquerading on some random network appliance, just that you probably want to switch it off (presuming you don't need it for something else ... really hard to guess from here). As for the matter of DHCP, there are valid uses for non-static IPs, and there are cases where assigning static IPs (with DHCP, if you are so inclined) makes more sense. If you use non-static IPs, you will need some method of resolving host names. That could be DNS or WINS. Frankly, my knowledge of BackupPC's handling of 'DHCP' hosts is somewhat limited, and I don't much care about the topic, because I would avoid using it if at all possible (I *can* read config file comments, though). But that is your choice, as is the setup of your network. I can tell you this much: if your client host had a static IP (whether or not assigned by DHCP), things would be simple. What is your $Conf {DHCPAddressRanges} set to? Does your host have the 'dhcp' flag set to 0 or 1 in the hosts file? > Go figure. :) That's the whole point.

Hint: without the *forwarding*, you wouldn't be able to connect across the VPN.
