RV340 hang when using VPN site-to-site

[Catalin Burla]

Hi. 

For +5 years I manage a farm of various RV routers with VPN site-to-site. Around 700 locations connected to HQ , at the beginning with Linksys routers then under Cisco brand. RV042, RV042G , RV320, RV082, RV016, all of then are online 24/7/365.

With every launch dual-wan+vpn device I replaced few working routers and become more or less a "tester", eager to get the increased performance and stability. 

RV320 was released with a broken firmware regarding VPN connections: if using more than 2-3 VPN tunnels suddenly hangs. I opened a case and it took more than 6 months to see a working firmware while I put my infrastructure at Cisco disposal to investigate and test. 

When RV340 was announced I was glad, the 100 Mbps VPN barrier was exceeded. I ordered 5 RV340 and 3 RV345, waited  3- 4 weeks for delivery and.... RV340 has also a broken firmware regarding VPN connections: it suddenly hangs, down not respond to ping, does not load interface , no traffic, nothing. It can work for 1 day to 10 days, but for sure it will hang. For more than 2 months I still insist using RV340, but I think next step is RMA . It's the same behavior that RV320 had ! I am using RV340 only for 9 VPN  tunnels over MPLS lines, no other traffic thru this unit. All 9 MPLS connections cumulated are about 100 Mbps and most important router is freezing during working hours BUT also on night hours when traffic in ZERO.  

I somehow contacted Cisco Romania, they told me that I am not the only one complaining.

I tried to open a case by phone on Cisco, the guy asked for service contract and I don't have one. 

If somebody else run into same problems please share . 

Best regards,

Hi Martin

thx for the quick response.

I don´t have any webfilter/AV etc enabled. The license also shows: Evaluation Mode (78 days, 21 hours, 2 minutes, 11 seconds remaining)

I´m not planning to use this features.

I will try to capture WAN Traffic when the issue accures. I have enabled debug logging and sent to a syslog server. So if this log´s also help I can provide them.

Hi Martin

Today I had the issue again. For about 7 minutes issues with reaching wesbite on the outside.

I figured out that the connection issues seem to be mainly with https Port 443 - other ports like 25 worked.

I also managed to do a package capture and see many errors with remote tcp port 443 - so there seems to be a problem.

Also the Packet Errors on WAN port in the RV340 GUI raised up from 530 to 2903 on WAN1 Interface.

I will now try to open a support case - I have to add that I´m not a business customer - I use it privatly at my home.

Even the TAC Case is open, log files and debug info sent, not much is happening from cisco side.

Today the RV340 crashed completely - with rebooting itself.

Info from the log:

I think this RV340 is really a bad choice!!

I haven't been on here for quite a while but have updated firmware on all of our RV340 routers to Firmware Ver 1.0.3.16 and all VPN Client to Site & Site to Site have been stable for quite some time.

I've done the same. But, I'm now unstable.
