Hi-
I'm hoping i can get some help for an issue i'm having. I'm double natting with a verizon action tec router and my cisco asa 5505 behind that. I had everything working when i had a linksys router/wifi AP , but i pulled out the linksys and put the asa 5505 in it's place. I thought i had everything looking good, but, it doesn't work. When the outside interface is set to dhcp it works. but later on i want to add port forwarding to my network, so i want to get the outside interface of the cisco asa to 192.168.1.251/24
Here is my setup:
internet > fios action tec router > cisco asa 5505
i've got a dynamic IP from Verizon > the action tec router hands out IP's in the 192.168.1.2 -192.168.1.250 /24 subnet. the action tec is 192.168.1.1
the asa outside interface is 192.168.1.X/24 (it's getting it via dhcp from the actiontec) and the inside interfaces are 10.1.1.2-10.1.1.26. Mangement interface is 10.1.1.1
Everything is working fine, but, when i change the cisco outside interface to a static IP of 192.168.1.251/24 i can't get out onto the internet. If i set the outside interface back to get an IP from the action tec, the interface comes up and i'm fine on the net.
