I had perfectly working DMZ on a WRT54GS
I use it to connect to an FTP on a LAN network different then my.
Not sure what happened and why it stopped but if I lets say get a Netgear and DMZ it works perfect for the same FTP server.
WRT54GS was with original firmware I decided to upgrade it to dd-wrt 23 micro to see if that will fix the DMZ but it did not!
Can I run some command to see if the DMZ is really working? I tried port forwarding aswell but to no success.
What do I need to provide here so someone can help me
The first thing you should do is upgrade it to v24 RC7, most people here are using it and it will make it easier to figure out whats going wrong if we are all on the same version.
I would also give up on using DMZ, its an easy fix but its inadvisable to use it for anything beyond basic testing. Port Forwarding is much more secure and should also decrease the load on your ftp server (which is otherwise receiving every connection that the router might otherwise drop.
Also make sure that the default gateway is setup correctly on your ftp server. Does your ftp server provide logging? If so you should be able to check if the server ever received the ftp connection or if it was blocked by the router.
Are you using passive or active ftp? If you are using active and you also have a direct internet connection on the client side then port forwarding should be more than enough.
If however you are using passive or your client doesn't have a direct connection then you need to setup port triggering (you could use port forwarding but this is pretty much what port triggering was designed for so you may as well use it). You need to find out what ports your server is using for pasv ftp and then setup the port trigger for these ports.
Gateway: 18.104.22.168 (Gatway of (B))
So I had on the Linksys DMZ Enabaled 22.214.171.124 (the ftp server) and when I ftp 172.17.1.222 I want to connect to 126.96.36.199
Everything was working perfect until it stopped We have not changed anything on the 2 netwroks (well at least I hope we havent)
I am lost!!! Ftp server log shows that there was interent connection from 172.17.11.15 (my laptop) but then my laptop did not receive response in 30sec and timed out... and thats whats happening...
