Hey,

We have a DFL-210, working fine for many years.  But we have a problem setting it up for our new VOIP-system. 

The DFL-210 is running firmware 2.27.03.25-14787.  We have a Asterisk server connecting to an external SIP-provider.  We set up our DFL-210, following the example and directions in the manual.  Outgoing calls are working fine.  Incoming calls are forwarded to the Asterisk server, but on a random port in stead of the 5060 port.  When tested without the firewall, calls do arrive on the right port.

Anyone else had this issue?  Is this an ALG issue and is there a way to force the use of port 5060?

Regards,

Lieven

How you configured SIP?

Manual has an example for your situation
NAT lan/lannet wan/all-nets sip-udp
Allow wan/all-nets core/wan_ip sip-udp

Thanks for your reply.

We did follow the example in the manual.  The NAT and allow rule are configured as you mentioned.

In the sip-upd, we set the destination port to 5060, but this seems to be ignored.

...........  Incoming calls are forwarded to the Asterisk server, but on a random port in stead of the 5060 port.  .......?

Try

SAT wan-allnets --> core-wanip sip-udp.
ALLOW wan-allnets --> core-wanip sip-udp.

Check, maybe you have some IP rule(s), which located before SIP and make it not working

SAT wan-allnets --> core-wanip sip-udp.
ALLOW wan-allnets --> core-wanip sip-udp.

SAT is possible only without ALG
