For the past week, I've been experiencing intermittent problems surfing the Net from behind my Astaro box. This seems to happen primarily after the machine has been idle for awhile. When I attempt to surf to sites such as google, yahoo or ebay, IE simply times out. So does a trace route, getting no further than the firewall. Then, things start happening for no rhyme or reason I can see. One site will start working, then another, then all, then one site will no longer be accessible, etc. This doesn't appear to be a DNS problem as the site names seem to resolve just fine when the sites are inaccessible.
I have made no changes to the firewall configuration (HTTP proxy is off). However, I did install the last three up2date patches last weekend. In fact, after installing the second patch, I was unable to connect to the firewall from one subnet and had to use a machine on a separate subnet/interface. The next day, the connection from the first machine was working again.
A couple more symptoms I have noticed. The little mail monitor program I used to track receipt of mail in various external mailboxes I have never has problem connecting to the external SMTP servers. However, Outlook will occasionally have trouble connecting to the same servers to retreive or send email.
Also, when I can't surf out to the site, a trace route from the firewall completes successfully.
I am stumped. Does anyone have any suggestions or ideas? Thanks.
