If traffic cannot reach the MX on these ports, the connection will time out and fail. Solution: Ensure UDP ports 500 (IKE) and 4500 (IPsec NAT-T) are being forwarded to the MX and not blocked. More information about setting the shared secret can be found in the links at the top of the page. It must match between the MX and the client. Solution: Ensure that the shared secret is configured correctly on the client machine. Incorrect secret key (preshared key in Windows).This issue may also result in no event log messages if the client's traffic doesn't successfully reach the MX's WAN interface.

Installing VPN client on another computer in the house. As I mentioned, the problem went away over the hotspot, but this wasn't a viable permanent solution. Countless reboots (computer and router).

Changing wireless password to kick all other devices off. Installing a brand new wireless router. Really sorry I can't help you further, but here are more things I tried, but failed to fix the problem. I haven't heard of anyone else who's experiencing this issue with this company and once they were able to point the finger at my ISP, they gave up on me. I forgot to mention in my post that I was somehow a unique outlier, connecting with my personal computer (as a consultant). I don't know much about VPN administration, but I wonder if the administrators are forcing UDP/DTLS. I'm sorry to hear that it's not working for you.

If the DTLS tunnel cannot be established or it is dropped at some point, the client fails over to TLS and adjusts the MTU on the virtual adapter (VA) to the TLS MTU value (this requires a session level reconnect).īlock UDP (in & out) for VPN client in Windows FirewallĬ:\Program Files (x86)\Cisco\Cisco An圜onnect Secure Mobility Client\vpnagent.exe Client retransmits the in intervals of 0.3, 0.6, 1.2, 2.4, 4.8, 9.6 seconds, and then sends a RST.Ĭisco vpn client tls every 20 seconds no ackĪrticle above references this, which was the most helpfulĪs long as DTLS is enabled, the client applies the DTLS MTU (in this case 1418) on the VPN adapter (which is enabled before the DTLS tunnel is established and is needed for routes/filters enforcement), to ensure optimum performance. Noticed that most application traffic happens via DTLS (OpenSSL) over UDP, but every 20 seconds, there's a TLSv1.2 transmission from the client, but no response from the server.

Anyway, I decided to live with it (for far too long) until I could do some troubleshooting myself and figure out next steps. It would be easy to blame the ISP because the problem didn't happen over my hotspot, but I can't help but think that the VPN server wasn't configured to properly handle such situations. Both essentially were pointing fingers at each other. I had troubleshot this with my ISP, Comcast/Xfinity and my customer (whose site I was connecting to via VPN). Total reconnect time was only a few seconds, but you can imagine how having your concentration broken every three minutes is a productivity killer! Symptoms were that my An圜onnect client had been disconnecting, reconnecting every few minutes (2:50 to be exact!), which would, in turn, timeout my RDP session. This one drove me nuts for the longest time until I found time to dedicate to troubleshooting it myself.
TL DR If Cisco An圜onnect is disconnecting, reconnecting every few minutes, try blocking UDP in/out ports for the vpnagent executable/service.Ĭisco An圜onnect Secure Mobility Client version 6
