<DIV><FONT color=#000000 face=Arial size=2>Does anyone know, how to use Linux as a transparent router or proxy? I´ve no problems with the routing-table or something like this (The right Kernel is also compiled and installed). The problem is, when I use the Linux system as a gateway in a small LAN, everything works (http, gopher, ftp,..) but news,SMTP and POP3. The PCs behind the gateway (my LAN), aren´t able to find the ISP mail server or news server.</FONT></DIV> <DIV><FONT color=#000000 face=Arial size=2>So I hope that anyone of yours knows the problem and how to solve it. Maybe (and I believe so) this is a generally problem and I might have only to kill sendmail or somethong like that (I stopped sendmail but it still does not work)</FONT></DIV> <DIV><FONT color=#000000 face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>So I hope some of knows the answer, which shall be posted to <A href="mailto:br@mycity.at">br@mycity.at</A></FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>regards</FONT></DIV> <DIV><FONT face=Arial size=2> </FONT></DIV>
