Unable to access Router Interface Public IP address from LAN

jamaludeen_s

Level 1

Hi,

I have router with two DSL Internet connection  (ISP-1 , ISP-2) ISP-1 with Static IP address whereas ISP-2 with Dynamic IP address. 

ISP-1 is dedicated for Exchange server traffic (NAT is configured on Router to access Exchange server from outside- Internet)

ISP-2 is used for employees Internet access.

From Internet users are able to access Exchange server.

Users from office LAN access the Exchange server using its public IP address (ISP-1 Static IP) and it’s not working, because when the traffic reach the router the public IP address is router Interface IP address.

Also we don’t have registered Domain to play around with DNS settings.

I tried configuring route-map it doesn't work since the destiantion IP address is there in routing table..not sure about vrf

Is there any way to make it work.

Thanks in advance

Jamal
