Newbie:windows update https fail

[ddantoni]

Hi,

I have a Cisco 837 router with IOS v12.3T(11).

I can't establish connection to certain https server as WindowsUpdate for exemple (When I check updates, an error Ox80072EE2 appear). I think that the problem is on inspect rules because the problem not appear on my bank https site.

I tried to set inspect rule on eth0 and Dialer0 interface and tried to remove ip inspect but the problem persist.

If there is some optimization or security improve to do on my config, it involve me.

My running-config is in attachment.

Thanks lot of.

PS : Excuse me for my bad english, I am French.

Hi

Try permitting HTTPS inbound also. Log it for any hits.

Cheers,

I have found the problem.

The problem was MTU on dialer0

I have changed ip mtu 1452 to 1492 and it's ok.

bye
