Port forwarding problem

[Seveas]

I've read other posts about my problem, but have not yet found a solution. So here is mine:

When I forward a port to a local IP-address, say port 21, the forwarding works from the outside. But i cannot use the external ip-adress from the inside.

Example:
ISP IP-address: 213.73.236.154
IP of server: 192.168.1.2
Random *external* IP: 146.50.9.20

146.50.9.20 -> 213.73.236.154 is forwarded correctly
192.168.1.* -> 213.73.236.154 is NOT forwarded. It gives me connection errors and port 80 shows the wl500g configuration page.

I am using Oleg's latest firmware and the router is in home gateway mode.

iptables -L -v -t nat says:

What should i do to correct this?

The feature you need is called "NAT of local connections" and is currently not compiled in to the linux kernel used by wl500g.

[Seveas]

Are you planning on compiling it into the kernel, it would be very useful. Just like lots of other things you already did :)

[Oleg]

There should be also changes in the firewall scripts, but nobody is interested in this... I'm too lazy to dig into this stuff deeper. Volunteers needed. :)

[Oleg]

Seems I was wrong: we don't need NAT of local connections. In fact ASUS 1.7.5.9 firmware has this feature already. :)

[Seveas]

Nice :)
But than I would have to give up the ssh server and bootcmd's which i use for my own ddns client, so when can we expect 1.7.5.9 based releases of your great firmware?
