I’m trying to set up NAT so our SIP soft phones will work when on this local network or when in one of our remote offices using the same external IP 74.165.xxx.xxx
Everything works fine on the remote offices I just added the public ip’s to an address list:
chain=dstnat action=dst-nat to-addresses=192.168.88.248 protocol=udp src-address-list=ucm6102 dst-port=5060,10000-20000
But I can’t make it work locally. If I remove src-address-list completely that works but also opens it to everyone on the internet. I tried adding my external IP’s to the list 74.165.xxx.xxx/29 still nothing. I tried adding my internal IP to the list and that caused it to hang traffic to those ports locally. Given that the destination IP is on my mikrotik which is also doing the NAT port forward I’m not sure what is needed to make this work.
Any help on how this can be accomplished?
