Is it possible to establish a VPN using IPSec (or something else) between two pix 501 using dynamic IP addresses? In this case the ip address pointed by the DNS name is changed manually twice a week (this is easy for a non-expert network admin because it uses a web page to do it). My role is to configure his Pixs, but don't want to change ipsec peers configuration every week, so I would like to use a DNS name to do it.
My question is how do I declare a DNS server for a pix?
Also, I the comand "set peer" accepts two kind of parameters according to docs, a hostname or an ip-address, but docs don't says nothing about DNS server.
Re: Pix + DNS server + dynamic ip + vpn = I need help
The pix does not have such a DNS command as you are after. At least one of the pix's need to have a static address, otherwise you are going to have to manually change the ip every time the ISP changes the ip.
