Hi, about packert filter rule problem.

[Vincent Huang]

Hi, experts   I am surveying firewall product and feel confused in some concept, hope you guys can give me some hint about that..Thanks.   Customer had one RFP(Request for Proposal), list some spec. for firewall.I listed some points I am not so sure.   1). in setting up packet filtering rule, user can define if he want to accept, deny or drop it. what is the difference between DENY and DROP , one sale from IBM asked me "did DROP packet mean firewall just don't log it ?" I know firewall-1 can do it. but other firewalls seemed no, do you have anyother idea which firewall can DROP packet?(sidewiner , raptor or gauntlet ?)   2). user need telnet ,ftp , http transparent authentication in user and session mode. firewall-1 can do it. but do I have other choice? can sidewinder or raptor or gauntlet meet this ?   3). can firewall auto detect "mail relay " behavior? I think firewall-1 can not meet this...   these information is very important to us. please give me advice ASAP thanks....   Vincent Huang [EMAIL PROTECTED]
