why no posts guys
hey no one reply me … why???
not shore whats the problem lots of pics but not much information on the problem
the problem is often page or browse is fail or address not found i don,t no how to solve this big problem i think problem in DNS setting
can you ping that address at that moment?
the ping is very good but some times browse is fail .. like( when you open http://www.yahoo.com it’s work good and when open games in yahoo Possible work, or do not work as possible ) and other some times working good >… i hope you get me … sorry for my english
I would suggest to simplify your environment and start testing. Keep just 1 DSL and disable the rules and packet marks for the rest. Test that everything is ok. Then add a second DSL, enable it’s rules, etc. Test again. Add a third one, test… and so on.
It’s very important to have a good set of tests which should emulate what your users will do.
Good luck!
