Slow finder Browsing when accessing LAN via VPN connexion

I am running ML Server, latest upadte on a 2010 Mac Mini Server machine.

When I am connected to my network from a remote location via VPN, and I try to browse my LAN structure with Finder, it takes ages for the list of folders/files to appear and refresh.

I have checked my VPN configuration and tried different type (L2TP, PPTP) but nothing significantly differ in term of browsing speed.

I also appreciate that the network connection at the remote location, as well as the upload speed on my local network can influence the overwal browsing speed... but after several test, I confirm I have more than 3 Mbps bandwith for upload on the local network, and 20 Mbps minimum on the remote location.

I also tried AFP / SMB, but does not seem to change anything.

So, I guess I hope the Community has already experienced the issue and some of you guys may have found a workaround to this issue.

Many thanks.

Confirm the VPN DNS server is correct, as bad DNS settings can cause sluggish performance. I'd usually expect the VPN to use the VPN server on the target network, in this case.

IP 10.0.1.202 =Another mac mini has been set-up to provide redondancy of local DNS Server

VPN configured for L2TP and PPTP

VPN host name: vpn.domain.com

Is your VPN client configured for those DNS servers?

When The VPN conection is not activated, there is actually no DNS server configured in the DNS section of the VPN connection. But as soon as the VPN is connected, this section becomes populated by the primary and secondary DNS server and they appear "grey" as if it was some kind of default configuration. I will try to force the DNS by entering them manually in the configuration section, perhaps it will improve the robustness of the configuration...

why not try cisco ipsec

Input the following settings:

Interface: VPN

VPN Type: Cisco IPSec

Service Name: This can be anything, I left the default.

Edit the new interface details as follows:
Server Address: cisco.vpntraffic.com or other country vpn such as Portugal VPN
Account Name: Your vpn account
Password: Your vpn password
