Getting a Sonicwall To Stop Port Remapping Guidance needed
I'm pulling hairs out over sonicwall still remapping sip ports on our devices. I'll list out my steps so far, but if anyone has a successful guide to preventing ports from being remapped by this device on UDP please share your steps or review my own for missing ones.
-Checked off every single setting, ensuring that only sip transformations are enabled in this VOIP section of Firewall.
2)In Network-DHCP Server Settings-Lease Scopes
selected Add static
set IP desired under IP address, set MAC under ethernet address, left lease time at 1440, set gateway & subnet from CMD-ipconfig/all found data.
Added services: named R!ATAFaxUDP
5060-5080 UDP ports
4) -Network-NAT Policy/Rules (2 entries)
Named: No SIP Port Remap WAN-To-LAN & No SIP Port Remap LAN-To-WAN
Source LAN Destination WAN for Service R!ATAFaxUDP
Source WAN Destination LAN for Service R!ATAFaxUDP
Under Advanced for both of these, unchecked 'source port remap'.
Rebooted devices, issues persist. 😓
