Port forwarding - inside/out

pedja · Thu May 19, 2005 2:45 pm

I have MT as router for local network. It has dedicated public IP.

I've set MT to forward some ports to local machines. It works fine.

But there is problem, when trying to connect from local machines to MT's public IP to mapped ports it does not work. Previous router I used worked as expected.

How can i achieve port forwarding to work regardles if public IP is accessed from public network or from local network?

Here is an example rule I have:

add in-interface=internet dst-address=213.65.57.241/32:2401-2402 protocol=tcp action=nat \
to-dst-address=10.10.10.11 comment="cvs" disabled=no

chain=dstnat dst-address=61.x.x.179 protocol=tcp dst-port=4899 action=dst-nat to-addresses=192.168.4.10 to-ports=4899

Unfortunately I cannot understand the meaning of this parameters. I cannot see where to use these parameters. Can you elaborate a bit?

Sure I am setting dst-nat rule. MT is 2.8. It seems like a bug to me. I tried to install from scrtch and got the same result on plain MT. Mapping works fine from outside, but not from inside.

I noticed, when I try to access mapped port, bytes and packets count for mapping rule increase, but connection does not work. It seems like a problem responsing back through mapped port.
