Re: Network Browsing problem by VPN Client

NW browsing issues are rarely to do with the head-end termination device, so I'm confused you're actually seeing deny messages on the PIX (they may be unrelated and coming from internal devices though).

Please go through the following URL and make sure your clients are set up correctly:

Re: Network Browsing problem by VPN Client

I obtain deny message only when the VPN client try to search one inside computer by name (NET VIEW COMPUTER1).

Re: Network Browsing problem by VPN Client

Hi

This is the situation:

1)

The VPN Client send this command: NET VIEW COMPUTER1

The PIX log contain Deny UDP 138 - Deny UDP 137 - Deny UDP 1056 - Deny UDP 1058

The VPN Client obtain error to browse network.

2)

The VPN Client send this command: NET VIEW 192.168.1.20 (COMPUTER1 IP Address)

The VPN Client obtain the browse of shred resource

Regards.
