ip passthrough not working

Novice
1 of 1

Hi,

 

i am running a centro with firmware 6.16.12

the centro has ip address 192.168.0.1 and behind my centro i run an router with ip adress 192.168.1.1.

 

I configured the centro to ip pass through to this router and i see in my router that the WAN ip is the same as the centro WAN ip.

 

Behind my router with ip 192.168.1.10 i am running a apache web server and the router is configured to expose he apache as virtual server.

 

Everything was running successful for a while and suddenly it stopped working.

 

Somehow my web server is not anymore accessible from outside.

I have done the following during trouble shooting:

I can access the web server from the inside LAN under the dynDNS name.

I cannot ping my external IPv4 address of centro from an external server ping.

 

What could be the issue?

Any advise on how to further investigate?

 

thanks
