Hi Guys,
Ive successfully patched the kernel with
ipportfw ect, and I can add my ipportfw variables.
Im testing it before I go out on site to install
it.
On our lan, we have two public sets of class c
licenses, so we don't requre ip masquarding, but I wanted to see if the port
forwarding actually works before I go out onsite and install it.
Our setup is pretty much the following
:-
One linux machine "A" (203.xxx.xxx.51) connects to
our ISP permanently.
A test linux machine "B" (203.xxx.xxx.22) has all
the ipportfw patches applied and is "online" via gatewaying to linux
"A".
I setup an alias ip address on eth0:0 on Linux
"B" that isnt being used but, its an ip address that we also own.
(203.xxx.xxx.100)
when I issue :-
/usr/local/sbin/ipportfw -A -t203.xxx.xxx.100/21 -R
203.xxx.xxx.51/21, I would of thought that If i telnet to 203.xxx.xxx.100 the
telnet would of been redirected to our primary gateway machine (203.xxx.xxx.51)
, but it still just goes to 203.xxx.xxx.22 "B" linux
machine.
The on site job is using ip masqurading which I setup,
unfortunately I can't test it on that yet because they havent been allocated the
extra public IP address.
Should I be worried ? :)
