In one of my remote offices, I have a PIX 506E Firewall. It currently runs PAT for my internal nodes and it works fine. I have also set up a VPN tunnel between my remote office and my Corporate office. However, the ISP in the remote office does not offer any static IP addresses. Therefore e0 is dynamically assigned.
However, in the branch office, I need to be able to access resources behind this firewall from an external location.
With my Pix at my Corporate office I do a static one-to-one translation and allow the necessary port number through an access-list and this allows me access to my resources behind the firewall.
I guess my question is:
Is there anything I can do to access my internal resources on the firewall at my remote office or am I SOL?
