I'm trying to setup an ASA5505. At the moment I'm trying to have a DSL connection with an static IP till I get my leased cct. However the internet IP range the ISP has given me is not in the same subnet as the DSL IP. I tried switching setting the DSL router in to bridge mode, but then it shuts the internet connection all to gether.
I'm running out of options of how to set up the outgoin port of the ASA5005 to internet via DSL. Can someone put me in the right direction please.
Thanks in advance.
What are the capabilities of the DSL terminiation point ? If the DSL device has the ability to NAT RFC1918's/private IP's then you can have one private subnet behind firewall and one in front... DSL--->crossover>---outside firewall IP's 188.8.131.52/24 --- Inside firewall IP's 192.168.2.0/24. IPsec/vpn establishment through the firewall shouldnt be an issue depending on the ACL's/rule sets you have built. This depends on the type of DSL connection/DSL equipment.
