I have a friend that needs to access my SonicWall firewall (a black box)
that has ONLY a web interface at port 80. He needs to login there,
and then the firewall will let him telnet here.
His ISP proxies HTTP traffic, so he "arrives" at the firewall
with a different IP than when he telnets.
So I thought I can setup a simple ip forward rule on another machine
so that traffic to port 8080 (for example) of the other machine will be
transparently
forwarded to the firewall's port 80. This should be done without
masquerading.
Is this a one-line ipfwadm ?
How do I do it ?
Thanks, Adoram
P.S. The setup: Linux RedHat 4.2 with all the updates, 2.0.36
