PPTP-VPN

I had a look at this today and got it working OK.  Only problem is that it is disappointingly slow. One end consisted of a 56K S/W modem on a Win98SE PC connected at 48000bps to the Internet.  On the other end was my server running 4.1.2 and a 512/128k ADSL connection. A 217k file transferred at 2.4k/sec, which seemed like eternity, and at the time the "Internet" was fairly lively.

Last week I experimented with PCAnywhere 8.0 between 2PCs connected via 56k H/W modems over the Internet and I saw transfer speeds reported between 6-7k/sec, i.e. things happened fairly quickly, including screen redraws.

I guess with more bandwith I would have been impressed. Can someone comment on my findings and maybe even divulge a few "settings".

Did you have encryption on under PC anywhere.  PPTP uses 128bit encryption which will slow thing down alot.  I asked about lower encryption on here to get more speed, but I have yet to get answer back about it.  Try setting PCanywhere to 128bit encryption and test the speed

Thanks for your reply. The default setting was used ie. Encryption level=Pcanywhere. Can't find any other settings except "Symmetric" or "Public-Key". PCAnywhere32 like you suggest, must use a lesser encryption level or has some clever compression technology behind it.

Looks like VPN is only useful if one is desperate or has a fast connection both ends.
