Back up scenario with PIX 515E

[syedmansoor]

I am using PIX 515E. Internet connectivity is through satelite and is connected to the outside interface of the PIX. I wantto have a dial back up using normal Analog lines so that in case of satelite link failure pix can route the traffic through Dial up infrastructure which includes Cisco 1721 router ( with 4 async ports) and 4 US Robotics Modem.

client does not want to bypass PIX even in case of connecting to internet through dial-up.

.As far as i know PIX does not support any of the backup command like backup interface , dialer watch & floating Static routes.

Please let me know if there is a possible solution for this.Any Alternative solution.

The PIX doesn't support any dial backup features as you've mentioned. You would implement the backup interface on the outside 1721, and just point the PIX to it via it's default gateway next hop. The 1721 will do all the routing of the packets from the PIX, send it over the satellite link or the dial backup as necessary.
