A key one is a problem with FTP.
If I ftp from that host to another... no problem. Works like a charm.
When I ftp to that host (from either my internal 192 network or from the outside) it (ftp) lets me authenticate my user but when I issue a command (i.e. ls or put) the prompt respods with;
ftp> put test.txt
local: test.txt remote: test.txt
227 Entering Passive Mode (206,191,28,136,94,176)
and just hangs there.... dead... If I wait about 2 minutes the connection will time out.
Some background. I'm using IPTABLES (via the firewall.sh) script... but from what I can tell, the rules are open for FTP. and if they were closed... why would I be able to authenticate?
