say I want to enable some messenger such as ICQ on the server, how can I find out the port number they are using? and one more thing, I am not sure how packet filter works, but I am just guessing here. once I set up the filter, the ISA server will listen to the specific port that associated the port define in the filter. and when there is request, it will exam the packet and open that port for the application to access the internet, is that right? and how is packet filer associate/work with protocol definition? thanks -----Original Message----- From: Alexandre Cavalcante Alencar [mailto:alexandre.alencar@xxxxxxxxxxxx] Sent: Thursday, October 04, 2001 8:38 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: How to enable app to access the Internet through ISA? http://www.ISAserver.org Read the article that I posted in Learning Zone about this Best Regards Alexandre Cavalcante Alencar Technical Support / Coordinator Microsoft Windows 2000 Certified Professional alexandre.alencar@xxxxxxxxxxxx Phone: +55 (85) 296-9876 Mobile: +55 (85) 9995-3302 Aspec - Assessoria, Processamento e Contabilidade S/C Ltda Microsoft Certified Solution Provider / Microsoft Certified Partner Phone: (85) 254-3223 Fax: +55 (85) 254-4779 Email: aspec@xxxxxxxxxxxx Internet: www.aspec.com.br Brazil - Fortaleza - Ceará -----Original Message----- From: mike [mailto:kyu@xxxxxxxxxxx] Sent: terça-feira, 2 de outubro de 2001 12:03 To: [ISAserver.org Discussion List] Subject: [isalist] How to enable app to access the Internet through ISA? http://www.ISAserver.org After setting up ISA. my email client can't connect to the mail server and apps like ICA can't connect, how can I allow them to accees the internet? thanks ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: alexandre.alencar@xxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub') ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: kyu@xxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
