We run an ASG220 with firmware 7.103, and just today started having an issue with a client who connects to our VPN from her home. This connection has not had any issues in the past, but recently she reformatted her machine (it's a laptop running Vista) and today, about 5-7 minutes into her connection, she gets a 'disconnected from VPN' prompt. I've searched and found many threads linking to a post about increasing the timeout threshold, all linking to this url: https://community.sophos.com/products/unified-threat-management/astaroorg/f/58/t/55608 - which apparently doesn't exist anymore (many of the posts were from '03, so not really surprising).
When she connects, her IP is assigned as 10.0.2.2, so I tried a ping -t from my computer to her while she was connected. Had a stream of replies, but then started getting timeouts. About 20 seconds later, this came up in the PPTP log from the webadmin:
