Connecting Navision Server using iPassconnect with Cisco VPN

nasheer

Dear All

Good day.

I need your help to clarify the below.

One of our Customer using iPassconnect VPN to connect
Hong Kong office to Malaysia Office Server. They facing performance
issue. The accessibility of Malaysia Nav Server is much slower.

And they tried with SonicWall VPN, connecting faster to the
Navision Server.

Can anyone help me to know why SonicWall VPN connecting
faster to Navision server than iPassConnect with Cisco VPN?

Is there any way to improve the performance in connecting Navision Server
using iPassconnect VPN?

Hope anyone can suggest the best way to overcome this problem.

Best Regards
Nasheer.

Are you using RDP? Are you using Citrix? Are packets prioretized?

Hi Rashed.

Thanks for your reply.
Here follows the scenario.

The user not using Citrix.

Navision WAN Connection via iPassConnect thru Cisco VPN
Users will login iPassConnect that established Cisco VPN connection to Hong Kong domain and also able to route to UK network. Server is joining the Hong Kong domain from Malaysia office.
Tested PING the Navision server require 800++ ms per packet replied.
Tried to access shared folder in Navision server, speed is acceptable.
Access to Navision client program à Login à Sales Order à view the Sales Order Entry menu, the process took more than 10 minutes.


Navision WAN connection via SonicWall VPN
Users will connect the SonicWall VPN client and direct connected to Malaysia – KL office SonicWall firewall.
Tested PING Navision server requires < 100 ms per packet replied.
Access to Navision client program à Sales Order menu, process took 10 times faster than iPassConnect connection.


We tested remote desktop access performance is good.

Hope you can suggest

Best Regards
Nasheer.

do a tracert on packets and see how they flow through the network. You'll see where the bottleneck is.

for example tracert www.google.com in cmd prompt


Also for remote connection For Navision it is always suggested to use RDP or Citrix.

It sounds like you are trying to actually run the Navision client directly from the remote WAN location over the VPN? Navision is a pretty fat client. They suggest to run all clients on 100 MB connections. I can't see you getting anywhere near the performance you need with this scenario, if I am understanding your post correctly. You'll end up with severe locking issues.

Use Remote Desktop or Citrix.

On a WAN of 2 MBits, Navision takes about 30 seconds only to logon. Even on a wireless LAN of 11 Mbs Navision is slow.

As thaug said

Navision is a pretty fat client

it's optimize for LAN.

Terminal services or Citrix it’s the way to go.
