I could resolve DNS on my local subnet, and on the internet, but I was unable to resolve anything on the internal DNS servers at the main office that I was connecting to. ![]() Now on version 5.0.680 I was unable to resolve DNS on the other end of the VPN tunnel when connected. I thought my problems were over until I re-connected to test that the VPN was still working. I updated the first client and Success! I was able to connect, disconnect, and then continue to resolve DNS. ![]() I updated one of the client Macs to 10.6.5, but still no luck.Ī call to SonicWall ended up with them giving me a new version of the NetExtender software for the Mac, version 5.0.680. I started with a review of the release notes of the SonicWall firmware, which mention a problem with Mac OS prior to version 10.6.5 and NetExtender. I had already updated the endpoint device, a SRA 1200, and the NetExtender was whatever version came with SRA 1200 firmware SonicOS SSL-VPN 4.0.0.3-20sv, which was the most recent firmware available at the time of writing. Once the connection was ended, boom, no DNS resolution. ![]() The problem didn’t appear until after the software was connected to a endpoint, and then disconnected. The client computers were able to resolve DNS properly prior to installation. Over the last few days I’ve been running into a problem with Mac OS 10.6 clients and the SonicWall SSL VPN client, NetExtender.
