I had to make a rule for Opera M2

Hi,

I use Opera for browsing, news, RSS and mail. Allowing the application in LNS works for browsing, RSS and news, but not for fetching mail. I have to create a rule allowing in and outgoing TCP traffic on port 113 to be able to get my mail. Why is that? Also, how can I make this rule as restricted as possible? Using the Application setting in the rule interface and only allow Opera for the rule? Or?

TIA for help.

 

Here is a plain-English explanation of port 113.*

You may be able to leave things as they are--that is, continue blocking port 113, without letting the IDENT request through. If you do this, and everything works fine, you're all set. (Though you may want to add a rule that blocks port 113, without logging it--just to keep your log cleaner.)

But if you disallow port 113, and then have problems or slowdowns while checking your email, you'll have to create a rule. Just create a rule that allows port 113 on only the IP address(es) you use to check email. The easiest way to do this is to look on the LNS Log tab, and right click the port 113 entries, and create a rule using the menu that appears.

One thing you're not going to want to do is to add Opera to the list of applications that a rule applies to. This is because the list of applications is only valid until the listed application(s) are closed. So, if you close and relaunch Opera, it will be exactly as if you hadn't added it at all. (I've always wondered about this particular design choice of LNS.)

I really shouldn't post messages when I am incredibly sleep-deprived. Hopefully this was somewhat coherent.

* I do not make a habit of quoting GRC.com. Quite the opposite. It just seemed appropriate in this case.

 

nameless,
Happy Thanksgiving! When you are finished with turkey and pumpkin pie, could you try explaining the last part of your above post ones again to me as a non native-English speaker/reader.... I do not get your point. Why is it "exactly as if you hadn't added it at all"

Thanks

By that, I just meant that if you add Opera to a rule on the "Internet Filtering" tab, it will only have an effect until that copy of Opera is closed down. It is not a persistent, permanent setting.

 

nameless,
Now I got your point,
thanks
