Re: [AZ] VPN Connection Instabilities
said by tokk :
are you using Cisco VPN client? If so, try setting the connection to connect via UDP instead of TCP. Just go to the properties of the connection entry and there is a radio button where you can switch from TCP to UDP on the "transport" tab.
When I use TCP I get drops all the time, when I use UDP I can be up for days on end.
Speed/performance (at least on my work network) is the same on both.
that is, of course, if your corporate network personnel have configured the vpn concentrator to accept both tcp and udp connections. while the initial ike phase i and ii negotiations occur over udp/500, it depends on how the nat-t spec is configured. some use transparent tunneling over udp/4500 (non-500-isakmp in the cisco world) and some use the tcp standard (tcp/10000) and some randomize the tcp port to whatever suits their needs.
long story short, if your enterprise vpn doesn't support tcp connections (or udp), then no setting on the vpn client will make it support them.
