VPN Issues

Hello All:

Have a 1720 in front of a Sonicwall Firewall. Trying to establish VPN with Smart Card logons. Regular VPN work fine (no smart card authentication)

When smart card enabled on VPN server,logins hang with verifying username and password. Checking Firewall logs, I see fragmented packet protocol 47 being dropped which I suspect is the issue.

Questions

Can the router be causing the fragmented packet being passed to the firewall?

Why only with smart card logons and regular VPN is ok

Thanks

PS - maybe this is not the cause but it is the only desparity between smart card and regular vpn that I can see
