ISP change

[CConnect-cx]

We just changed ISP's because the prior used MAC-binding for WAN static IPs.
The new ISP assured us that they don't do MAC-binding for static IP. However, if I put in a static IP on the 3cx console, I can't make the inbound calls work.
Our new ISP is SHAW. We've even asked SHAW to turn on multi-home.

However, if I turn dynamic on on 3cx console, it shows the firewall static IP, and calls work. I can even reach 3cx management console remotely using the firewall's WAN IP. (Firewall is Pfsense.)

If the IP is set to static, I can reach the management remotely, using the firewall IP.

Any ideas? Thanks in advance.

OK.. I found that the WAN interface described in Outbound rule for pfsense is the firewall ip.
Does anyone have experience with 1:1 NAT on Pfsense. I know 1:1 is not recommended for 3cx.

Just so that we first get a better understanding of you configuration, could you provide the info mentioned here: https://www.3cx.com/community/threads/information-to-provide-when-requesting-help.67558/

Also, is the IP your ISP provides a Public IP which is then NATed to a local IP?
