I am thinking my router was hacked last night right after midnight. Here what I have. My PC web pages stopped working. I could ping 8.8.8.8. My PC is pointing to the router for DNS. I am thinking DNS was changed on the router. I have firewall rules to block any DNS but 8.8.8.8 and my ISP which have been in place since I set this router up. When I looked under firewall on the RV340 remote was turned on and I cannot turn it off. I have included a picture. I changed the remote to a couple of non-useable IP addresses. Also looking under system summary VPN status I see 1 VPN has been setup. I have never setup a VPN on this device. Looking under VPN status the configs do not show. I did post a message a couple weeks ago about seeing VPN traffic in the logs when I had no VPN setup.
I seem to have an issue posting pictures. The upload does not work. Since I cannot seem to upload pictures I will tell you under VPN status under System summary it is showing 1 L2TP, 1 PPTP, and 1 SSLVPN. I have no logs as they have already rolled off. My logs goes back to 3:00 am. It around midnight. Probably planned that way.
I was lucky I had ACLs to block other DNS servers before one of my PCs was hacked.
So I guess re-flash and reconfigure?

I have this same issue. It really makes the 'Email Logs' function unusable. Is there any updat from Cisco? I am running the latest firmware as of a check last night.
Thanks!

I just recently lost access to a web page site. I tried a nslookup and was getting request timed out. I rebooted the RV340 router and it fixed it. After the reboot I was able to access the site and nslookup started working. Why would rebooting the router fix DNS. I asked and the web site was never down.
