Might I inject that, unless there is some sort of out of the ordinary DSL service configuration, you could perhaps enable bridging on the 675 and assign the public address of the DSL service to the Ethernet port on the 675. This would then make it possible (provided you have more than just one IP address assigned to the customer end of the circuit) for you to configure the outside interface of the PIX with a public address, and the inside with a private address.
The alternative would be to purchase a SpeedStream modem (or some other compatible DSL modem) (off of e..b..a..y.. perhaps) and configure it for bridging. Then your public address would definitely be assigned to the outside interface of the PIX, and your problem solved. Just an idea though... you might have already thought of it. -Mark -----Original Message----- From: Andy Barkl [mailto:[EMAIL PROTECTED]] Sent: Saturday, January 04, 2003 7:07 PM To: [EMAIL PROTECTED] Subject: RE: PIX behind DSL router [7:60307] The DSL router is required to terminate the line and the PIX is needed by the customer. With only one Internet IP tied the outside of the router, I see this as a very common scenario. -----Original Message----- From: Brian [mailto:[EMAIL PROTECTED]] Sent: Saturday, January 04, 2003 4:08 PM To: [EMAIL PROTECTED] Subject: Re: PIX behind DSL router [7:60307] pix is a nat box, curious why youre doing that on the router?? double nat can work, havent heard of it with this combo though.
