internet connection NAT

Greetings,

i have 2 subnets attached to a cisco 2911 192.168.1.0 and 192.168.3.0

3rd interface is connected with a Modem with address 192.168.4.3 and 192.168.4.1 of modem.

 

there is already a NAT active in DSL modem, any chance I can avoid running NAT on router.

internet works only with NAT and Setting default route to Modem's IP. any chance i can remote NAT ??

 

update:

googling around tells me its a common issue "Double NAT". 

 

any way around for it ??

Hi , Do you have access to

Hi ,

 Do you have access to your modem , on your modem you need to do following 

reverse route for 192.168.1.0 & 192.168.3.0 pointing to 192.168.4.3

On LAN Segment you need to add two subnet 192.168.1.0 & 192.168.3.0 thereby your modem can do PATING . If this option is not feasible then you need to PAT your both Subnet with interface IP address 192.168.4.3
