OK, I finally got a DSL connection, and I set up a FreeBSD-router as a router, using NAT to give access to the Internet for my whole network. That works so far, I can connect via SSH, POP3 and so on. But FTP and HTTP make problems. Those two protocols can be used from the router without any problems, but the other computers on the LAN time out when trying to connect to any server. They _are_ able to connect to to the webservers of my provider (the german T-Online), but I don't reach any other servers. OK, there might be a proxy enforcement at T-Online, but this would not explain why I can connect to FTP- and HTTP-servers from the router without any problems. I tried to use the -nat option of PPP and natd, both with the same result. I set up a proxy for HTTP and FTP which both work, but this is not what I want. There are 2 other things that struck me. First, HTTP works with other ports than 80. There's a server at port 70 which worked just fine. Second, I can use a proxy server at T-Online and use this to go online. But looking at the router, there must be a possibility to use the computers behind the NAT-router without a proxy server because the router doesn't need a proxy, so why should the others need one? If you've got any ideas or need some more information on my configuration, please contact me directly, as my overall mail volume doesn't allow me to follow -net. Thank you. -- Karsten -- perl -e 'use Math::BigInt;$a=new Math::BigInt 1;print"Zahl: ";$b=<>;$a*= $b--while$b;print"Ergebnis: $a, Stellen: ".(length($a)-1)."\n"' To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
