Hi,

 

I am running a TP-Link modem and a Netgear router connecting to the TP-Link modem via it's WAN Port. I had various port forwarding rules in place on both the modem and router to provide web access to an application running on one of my pc's. until recently these port forwarding rules worked fine and now they fail.

 

I had a look at the DHCP leases on the TP-Link modem and the router wasn't there, but it did appear in the ARP tab. another device that was connected to the TP-Link modem and worked appeared in both DHCP and ARP. 

 

I have to say the Netgear router had a static ip set in the router's settings but shouldn't it still appear in the DHCP leases?

 

Any help is welcome

 

Thanks

DHCP = hands out IP addresses 

 

ARP = a protocol to get MAC addresses for the purpose of knowing where to send/forward packets
