Frequently Asked Questions
My connection times out at the beginning of connection establishment ("VPN Gateway not responding (Phase 1)") when using SonicWALL Simple Client Provisioning, but works fine using DHCP over IPsec.
SonicWALL Simple Client Provisioning requires VPN Tracker to send an initial data packet to the VPN gateway that is so large that it may be split ("fragmented") into two IP packets. Some routers are known to not let these packets pass.
If a router between VPN Tracker and the SonicWALL is affected by this problem, you (or your SonicWALL's admin) will notice no connection attempt arriving at the SonicWALL when Simple Client Provisioning is turned on (i.e. there will be nothing in the SonicWALL's log, and a packet trace will show no packets from VPN Tracker), but everything will work fine with DHCP over IPsec.
Routers known to have these problems:
