Another common issues is the MTU of the physical interface. Sometimes the end-to-end MTU
cannot be discovered correctly. If the MTU is too large, the VPN connection can get stuck
on large packet size. In a terminal session you notice this, if commands with only a few
lines of output go well, but larger output as created by vi, ls of large dirs or less gets
stuck.
In summary, I do not think its QF related, but has to do with your VPN connection.
BTW, which QF version do you use?
