We have a new ASA5510 firewall in our network. Some VPN Clients can connect successfully to the firewall, yet others can not. On some users they consistently can build a VPN, yet it "disconnects".
Some other VPN clients and our site-site work well.
Upgrading to the latest 5.02 VPN Client does not solve the problem. Of the people who can not connect, one person uses dial-up and another uses DSL.
Any suggestions would be appreciated?
