Hi, I'm new into IT and I was wondering if somebody could help me set up Port Mapping. Here's my scenario - We have set up an Asterisk VoIP server that uses UDP port 5060 and another port range, and we want any public incoming connections destined for our Asterisk server on Port 5099 to be translated at the firewall to go to our Asterisk server on port 5060. I have been using ASDM 6.4 but theres no easy way to do this (as far as I know, and why I've came here looking for an answer).
We have currently just left port 5060 open to the public (so our home workers can use our phone system) but really want to get this sorted ASAP due to SIP Bots that look for ports like 5060 that are open!!
Any help would be greatly appreciated and if anybody needs anymore information just ask!!
