What is this concerning? Your message is out of context.

Also what services? You opened up UDP? THe common services (http and ssh) that run on these ports are both tcp protocol.

its regarding an ssh connection for a third party smooze to help figure why i cant login using there access key to configure trunks with sipstation

I forgot to mention if you look closely to line 5,6
rules are duplicated upd and tcp protocols

Still don’t know what kind of box this is.

Is iptables running on it?

Is the box with the rules the default gateway of the PBX?

6

yes iptables are running
i believe the box with the rules is the default gateway for the
pbx thus this is the only and single box running

Is iptables running on the PBX?

can you refer a link that i can read on PBX Iptables

IPtables is not part of the PBX, it’s in the Linux OS it runs on. Just Google ‘IPtables linux sysadmin’ and I am sure you will get hundreds of tutorials.

Accept If protocol is TCP and destination port is 21-81 and source port is 21-81

I might be wrong, but you might need to change the source port to ANY. Someone who tries to connect to your system on 80 or 22 will not likely to have 21-81 as the source port.

I will be working on this all day today, i plan to remove any
Dnat rules and do some testing. It is my understand dnat rules
are of a higher priority than most other iptables rules and just added security.
I believe this may be my issue. if there is someone out there that
has functioning rule set that preforms well with sipstation,centos 6.3 and willing to share that info please post.
I am using version 1.610 of webmin
