Region : Italy

Model : TD-W8970

Hardware Version : V1

Firmware Version : 0.6.0 2.8 v000c.0 Build 130828 Rel.38099n

ISP : infostrada

If i define a portforwarding for a host in my LAN, the NAT association works good (i can reach my host from WAN) until the ISP changes external ip address of the router.

In that case I have to disable the portforwarding on that host and enable it again to reach my host from WAN.

It seems that the NAT table, where all portforwardings are defined, is not updating, when ISP changes external ip address .

Is there a solution ?

Thanks
