Strange VOIP Problem
-
Hi all,
I have a very strange VOIP Problem. Certain calls just won't get through to my PBX, allthough others do and I can call out.
It seems these calls originate only from a certain provider, wereas others work fine.
I've configured everything according to https://doc.pfsense.org/index.php/PBX_VoIP_NAT_How-toI have a zyxel modem in Bridge mode <-> PFsense <- VLAN -> PBX and all SIP settings have been made on the PBX only.
As I said, I can call out to everyone, others can reach me from mobile phones, just a certain set of incoming calls will not get through.In the PFsense firewall logs I see the following upon an incoming call from these particular callers:
Apr 7 11:36:51 WAN 217.0.23.100 <wanip>UDP Default deny rule IPv4 (1000000103) Apr 7 11:36:51 WAN 217.0.23.100:5060 <wanip>:5064 UDP Default deny rule IPv4 (1000000103) Apr 7 11:36:50 WAN 217.0.23.100 <wanip>UDP Default deny rule IPv4 (1000000103) Apr 7 11:36:50 WAN 217.0.23.100:5060 <wanip>:5064 UDP Default deny rule IPv4 (1000000103) Apr 7 11:36:50 WAN 217.0.23.100 <wanip>UDP Default deny rule IPv4 (1000000103) Apr 7 11:36:50 WAN 217.0.23.100:5060 <wanip>:5064 UDP Default deny rule IPv4 (1000000103)</wanip></wanip></wanip></wanip></wanip></wanip>
I have even put an easy rule into the firewalls, but this won't change anything.
States Protocol Source Port Destination Port Gateway Queue Schedule Description Actions IPv4 TCP/UDP 217.0.23.100 * WAN address 5064 * none Easy Rule: Passed from Firewall Log View
Does anyone have an idea on what is going on here?
Thank you and kind regards,

Does it work if you modify the rule to
States Protocol Source Port Destination Port Gateway Queue Schedule Description Actions IPv4 TCP/UDP 217.0.23.100 * WAN address * * none Easy Rule: Passed from Firewall Log View
Do you have a NAT/Portforwarding where you have to add the source adress too?
-
In addition to Birke's questions, which interface did you add that rule to?

NAT is not the best option to have VOIP server. NAT can have same bad influence in VOIP Package and hard to debug.
I my opinion just bridge WAN Port with the port that you have your VOIP server."Create a DMZ"
And than you can use the static IP from your ISP direct on your VOIP server.Same Sample info about NAT and VOIP
