i want to configure site-to-site ipsec vpn on ASA 5520 for remote branches. Earlier there used pptp clients connect through firewall to inside pptp server. For translate pptp session to inside server, through ASA i must use static nat, because it use GRE. Maybe someone knows how i can simultaneously use old pptp connections and ipsec site-to-site? Is there a possibility to disable nat for ipsec, and enable static nat for pptp connections(nat policy?)if have only one outside IP?
thanks in advance.
