I have an ASA 5505 configured with Site-To-Site VPN to an ISR at headquarters (Remote Site to headquarters). The VLAN2 int is configured with a public IP to the Internet router . This public IP was given to us by the client, where we are leasing the office spce from, but now the client will be changing data providers and won't give me a public IP to use but he would provide me with a private IP. My question is it possible to use a private IP to re-establish the Site-To-Site VPN connecting to the ISR at heaquarters?
Thanks in advance,
