Hi, have a trunk configured with a provider that uses multiple IP addresses which is causing a bit of a headache for my incoming routes. Have searched the forums and from what I can see there are two options:
1.) allow anonymous access on FreePBX and restrict IP access ranges via firewall
2.) create new trunks for all provider IP addresses
Option one is possible but would rather not allow anonymous access at this stage if possible. Option two is not so feasable as they have around 4000 IP addresses (Telappliant).
So I guess my question is whether there is another method other than the above or a way to specify IP ranges to authorize as opposed to individual IP ranges within FreePBX?
Many thanks in advance!
