Hi
I have been fighting to get a vpn (or similar) connection working with a known remote IP address.
I have a 5.5 (soon to be 5.6 box) as the server/gateway on dynamic adsl. Remote location connects via a 5.6 box, modem dialup - client/gateway. I run my own homegrown dynamic dns setup so have provided both machines withy a fqdn (mine provides some key extra things that the freeby dyndns don't).
A W2k user at the remote location can connect to the server/gw with a vpn and get a good connection. Stable and now generally lasts at least half a day often a full day.
The user then telnets into an internal server for a particular in-house application and all works fine. Significant issue is the internal server then needs to print back to the user to a fixed IP. I have set the server/gateway to dish out 2 dhcp addreses and it alternates. If I set the high and low to the same IP it still dishes out from two addresses. The remote user now knows that if printing doesn't work then drop/reconnect and get 'the other address' and all is ok.
Now I need to add another remote location for the same setup so the printer address issue is now a major problem.
I have now been trying to set up an ip/sec (freeswan) connection to try that. Issue still seems to be how to provide a known ip to the remote user. I investigated IPcop but the same problem exists.
If I could do it via the vpn/pppd I would use that but from my testing it clearly just uses dhcp. Since a mac address isn't the basis for the ip received I can't fix the dhcp provided address.
Any ideas will be appreciated.
