We have acquired a new office and need to figure a couple of things out for connectivity. We have our existing service provider installing their services at our other location. We have an ASA5510 at our existing location and the ISP has installed a switch, which has 3 ports going to 3 different interface ports on the back of the ASA. Each is it's only VLAN, one going to the internet, one to our backup provider, and one to a private WAN. The 4th interface port on the ASA goes to our internal network. So all of the interface ports are full.
At our new facility, we have a PIX515E firewall, which has only 2 interface ports, one for internal, one for external.
So, the problem is, we are trying to have the ISP provide a private line to us from the remote facility, and still have another outside line for internet use for that facility. Any ideas on how we can accomplish this with only having one port for external use on that PIX?
