RV082 - Multiple unexplained policy violations

    I have an RV082 with the most recent firmware (1.1.6.14).

    The router seems to be randomly blocking outgoing connections (to websites like Google and other legit sources). I have turned off SPI and all keyword/domain blocking features. I have not made any changes to the settings of the router other than changing the LAN IP, setting up the WAN info, disabling DHCP (we have a W2K domain controller that handles that), setting up 1-to-1 NAT for three servers on the LAN side, and setting up the allowable incoming services for each of those servers.

    The only security restrictions I have in place are rules that dictate the allowable inbound traffic (Citrix,POP3,IMAP, etc.), and blocking all outgoing port 25 traffic with the exception of our mail server. These all seem to work (when tested, I can go out on 25 from the mail server but no other machine). However, about half the time I try to go to a web site it doesn't work, and checking the log will show something like "Connection Refused - Policy Violation: 10.1.1.44:1215->66.102.7.99:80". However, the router shouldn't be blocking ANY outgoing connections unless they're on port 25!! It got so bad that the internet was nearly unusable and I had to temporarily replace the router with a (ugh) Netgear.

    I can run a ping window that continuously pings our DNS servers (outside the LAN) even when the websites become innacesible, so I know it's not a connectivity problem. The router is definitely having some weird problem.

    Any suggestions would be greatly appreciated!

    We have the same issue (firmware 1.1.6.14).

    We had "Connection Refused..."messages for incoming SMTP inbound traffic despite having forwarding & rules.

    We have contacted Linksys, the support we got was at best useless, at worst stupid.

    We tried all configurations and the only (bad) workaround we found was to disable the firewall !

    I too have given up on using the firewall capabilities in the RV082. Linksys is piss poor when it comes to troubleshooting these issues.

    Additionally I get a lot of errors like this:

    Failed nat control SIOCADNAT - Success
    Error in RNAT configuration Local Servers
    RNAT configuration failed
    NAT configuration failed


    But I found in one case it is caused by port forwarding the builtin DNS/UDP/53 service.

    I went so far as to reset my router to default config and then reconfigure, but it did not help.
