Router Info

This page contains general information about port forwarding and disabling application layer gateways on particular routers.

Mikrotik

This router has an ALG that can be disabled with the following command

• /ip firewall service-port disable sip

The info was found at the following two links Mikrotik Wiki Mikrotik Forum

Fortigate

I found this online about solving issues with Fortigate routers and NO AUDIO with remote SIP:

In the command line of the fortigate type the following:

• config system settings
• set sip-helper disable
• set sip-nat-trace disable

Reboot the device

In the command line type the following:

• config system session-helper
• show

(now look for SIP, mostly it will be "12")

• delete 12

Don't use any protection profiles on the firewall of the sip rules.

Cisco Pix 506/501/515

This is for Pix 506/501/515 but it should work with any Cisco Pix, and possibly other Cisco

routers.
