Routing behind a firewall ?!

Routing behind a firewall ?!

Post by Tuvik Bek » Mon, 09 Oct 1995 04:00:00

Hi all,

I'm connecting my standalone PC to my university cc by ppp. The dialup server
has a firewall implemented, that prevents direct contact to a large range of
remote hosts (in fact I can only directly connect to hosts in Israel, with an
address that ends with '.il').
If I want to telnet a '.edu' address, for instance, I have to first login to
a local (.il) account, and then telnet from there. As for other tcp/ip
applications - the problem is easily solved if they know how to use a proxy
server (as netscape does).

While working in Windows, I worked around the problem by obtaining a set of
applications that all knew how to utilize a proxy server. Now I switched to
Linux and such apps. seem hard to find... (except netscape, of course :-)
I wondered if there is any more general solution to the problem - something
like specifying a route like:
local PC-->dialup server-->local (.il) relay-->out to the world
I have no idea if this, or any other general solution, is at all possible,
but would like to hear any suggestions.

Alternatively, I'd probably have to settle for a bunch of net apps. (ftp,
finger, etc.) for linux, that know how to handle a proxy server. If anybody
knows of such apps. please let me know.

Many thanks!

: Hi all,
hi tuvik,
        Maybe you should try and get socksified binaries. Provided
that the firewalled site runs a socks-server ...

1. FreeBSD and natd - routing from behind firewall to behind firewall.

Having a strange problem with a FreeBSD gateway/firewall system I set up.  
The gateway connects a small network to an ADSL line and has three static
external IP addresses.  I am using natd to provide access to the Internet
for computers in the internal LAN.

One of the machines behind the firewall is a web server and I use a natd
line similar to the following to route incoming connections to that box:


In this case the real IP of the web server is and it is
accessed from outside the LAN by the address  This works.

The problem is that if any of the computers on the internal LAN try to
access the web server at it doesn't work.  I can access the
web server fine from inside the LAN using the local address (

I suspect there is a simple solution to this problem.  Can anyone explain
what it is?
