I am setting up an ADSL connection with a Cisco SB-107 router. The ADSL line is configured as RFC 1483 (routed with LLC) - see config below. This router is in front of a Watchguard firewall. My ISP gave me 2 IP addresses (1 for the router and 1 for the firewall), however I'm having huge issues with NAT and can never get through to my email server. What I want to achieve (very simple) is to be able to access my email and web server from outside my network using the secondary IP address (128.**.**.96). I've tried several different configs on my router, without success. Can any correct my config below? Any help would be greatly appreciated.

ROUTER IP: 77.**.**.130/
FIREWALL IP: 128.**.**.96/

!This is the running config of the router:
