I am new to this forum and just register myself to get some help from you guys.
I have Cisco ASA 5510 firewall and I have site-to-site vpn with my headoffice in US with same model of firewall.
unfortunately I have to change my firewall wan interface IP address for better service.
If I make this my site-to-site vpn connectivity will goes down.
I need to find out whether I have to remove site-to-site vpn configuration at my headoffice and reconfigure it or is there any option that I can modify only peer IP address at my headoffice because I am not changing any configuration in my firewall except the wan interface IP address.
