The VPN has MTU larger than MTU of physical network. Lots of packets are
dropped as somehow VNC sends rather large packets. I had this problem
myself until I lowered MTU to below of the physical network MTU.
The symptoms were:
1. screen would render half way and then stop.
2. screen updates were extremely slow
3. Connection would go for some short time and then would be dropped.
I am not sure why MTU is causing that effect. I think that VPN packets
can not be fragmented so they are dropped and there is a large packet
loss. I am not sure how VNC reacts to large packet loss.

Can you provide any more information on why that causes the effect SB is

MTU is too large on your vpn connection.

Hi,
I just bought a new computer from Dell (Intel dual core
2.8GHz, 1GB RAM
running Win XP Media Center w/ SP2), and downloaded VNC 4.4
viewer on it.
When I VNC to my work machine, VNC viewer freezes
intermittently. Some times
immediately after logging in and some times after 10-15
minutes of work. Did
anyone here faced a similar problem? How do I fix this problem.
Thanks,
- SB
