LRT224 IP Protocol 4 forwarding?

I have a need to forward IP Protocol 4 traffic through the LRT224. Is this possible?

 

I have not found anything in the manual relative to IP Protocol 4.

 

 

Thanks

Mark

In the LRT it's call Port Address Translations or PAT:

 

Configuration => Port Address Translation

Are you sure? I'm not really sure from looking at the gui setup screen for PAT.

 

I'm talking about IP Encapsulation within IP (RFC2003.)

 

If you're right then I have a lot more reading to do. Please confirm....

 

 

Thanks

I've researched this and you may have to use the One to One NAT feature.

Ok, that's what I was leaning towards also. As a workaround, if I were to put a LAN address in the DMZ does the port forwarding take precedence over the DMZ host? In other words, would the router process and route packets destined to ports in the forwarding table and once all port forwarding has been processed allow all others to go the to DMZ host?

 

 

 

Thanks

I'm not sure on that but there is more information on the LRT DMZ in the below thread:

The above sounds right for the LRT routers.
