RE: too many open udp ports

If you are using the Winsock proxy client, then you may have additional
protocols open other than http and ftp.  I would also make sure that the MS
Proxy is NOT part of any domain, and block all TCP/UDP ports for NetBIOS.

Subject: too many open udp ports


Hi all,

When i port scan from inside a network and if the
proxy is on the DMZ the port scan reveals a lot of
open UDP ports. is this normal or does this mean a
security loop hole. the proxy is a MSproxy and the
scan was conducted from fscan inside the dmz. Can
anybody explain.

Pl don't mistake if this is a basic question as i am
very new to this feild.

 Regards
Vinay
