UK | Re: [Config] Firewall config or virus/spyware? Does no one have any suggestions? What is it about, eg, the sites that I have cited that causes the firewall to drop the connection? Are they trying to set up new connections to me?? | |

| Re: [Config] Firewall config or virus/spyware?Have you checked to see if the http app inspection policy is causing the problem? Try removing the http app service policy by applying this snip to the config:
Check to see if the problem continues. Since you're seeing two different log behaviors for the two different sites you're having problems with, it's hard to tell what's causing the problems. Also, if you're not running 12.4(15)T4, and are able to upgrade, you might want to do so to take advantage of the improvements to some of the logging.
Be sure to back up your config before you start. | |

1 edit | Re: [Config] Firewall config or virus/spyware? Very odd: I removed the L7 inspection, found I could access those sites, and added it back again, and I can still access them.
The only other thing that I changed in recent days is to go back to my ISP's DNS servers from OpenDNS... | |

| Re: [Config] Firewall config or virus/spyware? Have you tried switching back to those OpenDNS servers again and seeing if you can replicate the problem? It may help someone in the future who is having the same problem.
Also, when you noticed that the only thing you changed was the OpenDNS servers did you check with their website to see if they were having any problems that may be resolved? | |
