I have an ASA 5510 configure for remote VPN Client and site to site VPN (ASA 5505 to ASA 5510).
One of my customer's want to establish site to site VPN to my network , but it is not Working (no CISCO firewall).
He tell me if it possible to change my VPN configuration. He want to using VPN aggressive Mode instead Main Mode

Thanks for your help
