Ticket #4293 (closed defect: worksforme)
network down after vpn activity
|Reported by:||osipov@…||Owned by:||jamor@…|
Trying to create VPN server. Installed Zentyal, set eth0 network interface to internal and eth2 to external. Both set to static IP, adds gateway - our gate in external network. Then i added PPTP module, setup user for access - "vpnuser".
When i trying to connect to VPN from internet, using windows standard VPN connection, it connects all works fine first several minutes.
But when i start to work, after some time VPN-connection hangs and eth2 interface stops responding at all. While eth0 is working, i can access web-interface from internal network, but external don't respond. Web-interface Diagnostic tools -> Ping to any external site or IP says "Destination host unreachable". Only reboot of zentyal helps.
I noticed, that this situation occurs after some load on network. For example if i establish VPN connection and just run ping command on some internal server - this connection may live for several hours. But if connect to remote desktop and open some pictures - VPN will die in 1-2 minutes. It looks strange, but usual traffic i get through VPN connection before hang is 28 MB.
at dashboard both NICs says: LAN-eth0 Status up, internal, link ok MAC address 00:23:54:4c:78:e2 IP address 192.168.1.216
Status up, external, link ok MAC address 20:cf:30:d6:f0:bd IP address 188.8.131.52
Zentyal hardware: intel q6600 cpu, 4Gb ram, 1Tb hdd, onboard nic and pci nic.
