Guest Dave Posted September 25, 2007 Posted September 25, 2007 Using a default install of RAS, here is what we get: Transfer #1 test.mp3 100% 10MB 318.6KB/s 00:33 Transfer #2 test.mp3 23% 2508KB 4.57KB/s 10:01 (I killed the second transfer after 10 minutes, you get the idea) The connection in transfer #2 goes stalled randomly and then picks back up. Before you answer “your link speed is to blame” please note that the above proves this is not the case. Transfer #1 & #2 are connections between the same two computers, the only difference being, #2 is after connecting to the VPN. Transfer #1 is straight across the ‘net with no VPN. This shows that clearly, the link is not to blame or they would both be the very slow speed. That being said, where should I be looking on the VPN server? It’s a Windows 2003 Standard Edition box with all updates applied. The following are open on our cisco: permit udp any host x.x.x.x eq 1723 permit tcp any host x.x.x.x eq 1701 permit udp any host x.x.x.x eq 1701 permit tcp any host x.x.x.x eq 1723 permit gre any host x.x.x.x I can replicate this scenario with windows, mac, and from any location I have been to and tested (hotels, various homes, other offices...). I am at a total loss. Thanks in advance. DP
Guest Dave Posted September 25, 2007 Posted September 25, 2007 Re: VPN Slowness I have done some further testing on this issue and come up with the information below - I really have no idea what could be the issue... please help. We are dealing with 4 tests: 1) No VPN, from network to remote client 2) No VPN, from remote client to network 3) VPN, from network to remote client 4) VPN, from remote client to network Test results: 1) 100% 10MB 318.6KB/s 00:33 2) 100% 10MB 214.6KB/s 00:49 3) 23% 2508KB 4.57KB/s 10:01 4) 100% 10MB 191.2KB/s 00:55 As you can see, the ONLY problem is from the network to the remote client via the VPN... of course, this defeats the whole purpose of the VPN as probably 90% of the traffic is from the network to the remote client. This is killing me here. Any help is greatly appreciated. For reference, here is the router set up... x.x.x.x is the public address of the server that RAS is running on. permit udp any host x.x.x.x eq 1723 permit tcp any host x.x.x.x eq 1701 permit udp any host x.x.x.x eq 1701 permit tcp any host x.x.x.x eq 1723 permit gre any host x.x.x.x Dave wrote: > Using a default install of RAS, here is what we get: > > Transfer #1 > test.mp3 100% 10MB 318.6KB/s 00:33 > > Transfer #2 > test.mp3 23% 2508KB 4.57KB/s 10:01 > > (I killed the second transfer after 10 minutes, you get the idea) > > > The connection in transfer #2 goes stalled randomly and then picks back > up.
