internet proxy enabled to go outside world.

and i can run internet there using firefox and mozilla etc work fine

now when i try to run some test of telnet,host,dig,nslookup,traceroute
it return me below error, can any one advise what things to be check
missing or anything to install further to this. be advise and what
files on slackware linux workaround.

however the local lan same commands r working, but outside world they
did not work.

we allowed from firewall only port 110,25,443,8080,80 to go outside,
it wil be email server
