I have an RV082 (hardware version 1 - old gray and blue model) that has started randomly locking up after I added a third gateway to gateway connection. The routers on the other ends of the VPN connections are as follows:
RV082 (same model): static IP
RV042 (2012 model): dynamic IP + dyndns
RVS4000: dynamic IP + dyndns
The RV082 that locks up sits in a datacenter with a static IP. All three VPNs are configured with the following settings:
Local Security Gateway Type: IP Only
Local Security Group Type: Subnet
Remote Security Gateway Type: IP Only
Keying Mode: IKE with Preshared key
Phase1 DH Group: Group 1
Phase1 Encryption: 3DES
Phase1 Authentication: MD5
Phase1 SA Life Time: 28800
Perfect Forward Secrecy: selected
Phase2 DH Group: Group 1
Phase2 Encryption: 3DES
Phase2 Authentication: MD5
Phase2 SA Life Time: 3600
Preshared Key: some password
The Remote Security Gateway Type setting in the remote group setup sections vary on each of the three devices. The first one above has IP address by DNS resolved and the other two just have IP address set.
All three VPNs connect fine and work as expected, but the main RV082 periodically locks up with more than two VPNs connected. When the lockups occur the only fix is to power cycle the device. Since it sits in a datacenter that I'm not physically in front of I don't know what lights are blinking on it. The web interface does not respond when the lockups occur and pings either time out or the response times go up really high (6000ms or higher). That router is running firmware version 2.0.2.01-tm. Does anybody have any ideas as to what might be causing the lockups?
Thank you for reaching the Small Business Support Community.
I am not familiar with the hardware version 1, nor with the firmware release version you currently run. I would first suggest you to disable the Perfect Forward Secrecy and test it, if the problem persists then look under advanced VPN settings for "Dead Peer Detection" and disable it, test again, if still the same then disable "keep alive" and if you have IKE Negotiation settings change it from "Aggressive" to "Main" mode. Make sure all the routers have the same settings configured.
Other than that I suggest you to contact the Small Business Support Center to have a TAC engineer check this out;
