Example translating SIP sessions to a different destination port
To translate SIP sessions to a different destination port
- Add the static NAT virtual IP.
This virtual IP forwards traffic received at the port1 interface for IP address 172.20.120.20 and destination port 5060 to the SIP server at IP address 192.168.10.20 with destination port 5061.
config firewall vip edit “sip_port_trans_vip” set type static-nat set portforward enable set protocol tcp set extip 172.20.120.20 set extport 5060 set extintf “port1” set mappedip 192.168.10.20 set mappedport 50601
set comment “Translate SIP destination port”
- Add a security policy that includes the virtual IP and the default VoIP profile.
config firewall policy edit 1 set srcintf “port1” set dstintf “port2” set srcaddr “all”
Translating SIP sessions to multiple destination ports
set dstaddr “sip_port_trans_vip” set action accept set schedule “always” set service “ANY” set utm-status enable
set profile-protocol-options default set comments “Translate SIP destination port” end
