Hi Guys,

One of our client experiencing and intermittent issue with DNS results(Unable to resolve DNS addresses externally) while connected via Cisco VPN.

User can connect internal resources fine, intermittent issue accessing external Websites.

Ping, NSLOOKUP timing out intermittently

Cisco VPN Client used :- version 5.0.07.0290

Cisco ASA Firewall 5505 - Cisco Adaptive Security Appliance Software Version 8.2(2)
Device Manager Version 6.3(1)

Another user with same setting can able to connect and does not experience similar issue.

Tried the same Macbook(Using Windows 7) on different network ports, seems be still an issue.

Any idea/suggestions ?

Hello Uber,

Is he using an internal/external DNS while connected to the VPN Main office?
