I have created a successful IpSEC VPN tunnel between a Linksys RVL200 and ASA 5505 using the Site to Site VPN Wizard. After settings on both devices are matching, the tunnel connects but a client software on the remote site cannot use port 3306. Do I have to configure additional ACl / ACE policies to make the traffic enabled? I assumed (because I am a newbie) that once the private tunnel is establoshed, all traffic is allowed on the interfaces. I spoke to a L1 technician at the hosting facility and they said that the configuration needs tweaking because it is "dropping packets". The client software works perfectly fine when the RVL200 is connected to an RVL200 via an ipsec tunnel - so the only thing I changed was the ASA device.
I have this problem too.
