Firewall setup with Cisco ADSL router

I have a firebox X500 that I’m trying to set up with a ADSL Cisco Router. My private subnet is using the 192.0.0.1 Network. I currently have 3 static addresses being used: 206.27.10.122, 158, and 134. I have the firewalls trusted interface using an address of 192.0.0.254 and the external of 206.27.10.134 with a gateway of 206.27.10.133. Can’t seem to get past the router. What should my correct external settings be? The router information is below. Any help would be GREATLY appreciated. Currenly using a Linux box set up as a router with a lost pass so I can’t access to get its config info. I figure that its taking the 206.27.10.134 address but I’m not sure. The firebox is replacing this one. When implementing these addresses I can ping to the 206.27.10.134 IP but not the 206.27.10.133 IP. What am I doing wrong?
