We have a Sonicwall 2040. VPN is enabled and working. Created a new backup domain controller and took it to my home to test as a remote backup device. Can successfully connect thru the VPN network into the office network and start backups. However, after awhile (maybe about 1 hour) the DC is disconnected. I have the VPN timeout on the Sonicwall set at 28800 seconds.
The home network is commerical grade DSL (3.0gb/sec). The DC was direct connected with LAN cable into the DSL modem. Please advise. Thanks.
