i recently set up a obsd fw as a adsl fw/router to
protect my workstation and speedup(cbq) the network-
short and stylish:
anyone a idea how i can have a workstation behind
a router have the same ipadress assigned like the
gateway itself ?
the long story:
i am not a typical gamer, but from time to time id
like to play a round quake3 :) well, the problem i
ran into is related to this game. and the following
strange ip setup i desire is because of that game.
playing behind nat routers isnt working that good because
of some software namend punkbuster which "registers" the ip
(in my case. a private one) of the computer the game is
running on on some servers(to prevent cheating..whatever).
now with that private ip registered and the official ip
i got from my providers dhcp servers, i dont have much fun
playing because they dont match, i cant connect to 90% of
the available gameservers. (server may respond like hey
18.104.22.168 you havent registered yet because for the server
i am 192.168.1.10)
now i thought about how it could be possible to have
the same ip-adress on my firewalls external interface
and on the nic of the workstation behind it.
another thing to mention is that i have to use a pptp connection to get
connected to the internet. the offcial ip is also assigned to firewalls
has anyone a idea how/if this could be accomplished ? maybe with
bridging support ? some wild double source adress translation ?
black voodoo magic ? :)
thanks for any ideas
