One of the most common site-to-site VPN issues between a Cisco Meraki appliance and Microsoft Azure is caused by mismatched local/remote subnets, as described above. Once the VPN configuration has been completed on Microsoft Azure, check the address space(s) designated to traverse the VPN tunnel. Hello all..for some reason one of my vpn tunnels seems to go down every few hours. It is connected to a Wacthguard firebox on the other end. Our other tunnel is set up the same exact way and seems very solidwe never have problems with it. Jun 24, 2013 · If there is no interesting traffic going over the tunnel the tunnel can and will be taken down. I believe the timeout for interesting traffic is 4 hours. If no traffic was sourced or destined to the remote-side a VPN can be suspended. We setup our VPN sites in SolarWinds to ping the remote-side IP / Gateway to keep the tunnel up / going. A site-to-site VPN tunnel between them had been working flawlessly for about 2 years. Approximately one month ago, we began having an issue where the tunnel would go down, at around the same time of day everyday, and then it would magically heal itself and come back online in about 15 minutes. These were typically used with routers, because routers use Virtual Tunnel Interfaces to terminate VPN tunnels, that way traffic can be routed down various different tunnels based on a destination, (which can be looked up in a routing table). But Cisco ASA now supports Virtual Tunnels Interfaces (After version 9.7(1)) Advantages RE: VPN tunnel keeps dropping connections/sessions Helenp1983 (MIS) 28 Nov 07 08:40 With our old firebox III/1000 we use to setup a ping -t from one of our servers to cross the VPN to keep it open

Now instead of going down every hour or so, it lasts about 7 hours and 30 minutes. Also, I notice the tunnel takes around 10 minutes to start passing traffic once the firewalls show that its up. In other words, I'll reset the tunnel and it shows both IKE and Ipsec are connected, but I can't ping through it until about 10 minutes later.

Jul 24, 2017 · When deploying a VPN solution using the Cisco AnyConnect Client over SSL, using JUST the SSL tunnel makes things painfully slow - in the neighborhood of 1-2 Mb per sec, even if bandwidth is adequate on both ends. The key is to enable the DTLS channel that allows traffic to flow over a UDP tunnel instead of the SSL TCP tunnel (TCP over TCP issue). Jul 24, 2017 · This is going to be the first in a series of VPN posts focusing on the various types of VPNs one might see on the CCIE Security lab or on the job. I think it's important to have this overview because as you configure IPSec VPN or troubleshoot it, it'll help you to know what's going on under the covers of that configuration. Nov 14, 2019 · Virtual private network technology is based on the concept of tunneling.Just like a water pipe contains the liquid flowing inside of it, a VPN tunnel insulates and encapsulates internet traffic—usually with some type of encryption—to create a private tunnel of data as it flows inside an unsecured network.
