We've got one here........very good, but not cheap. -----Original Message----- From: Bob Peitzke [mailto:[EMAIL PROTECTED]] Sent: 31 October 2001 00:48 To: MS-Exchange Admin Issues Subject: RE: Exch5.5 and Linux firewall
Just get a Nokia firewall appliance that comes with CheckPoint Firewall-1 4.1. It's OS is a stripped-down version of BSD Unix, and even a dummy like me can manage the firewall through its GUI interface. Very secure, very reliable. We got the IP 330 model with 3 interfaces for private, public & DMZ. Works great.

I need one badly. If I had a secure OS I could spend 5-8% of my work time sleeping. ellery -----Original Message----- From: Lefkovics, William [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 30, 2001 10:54 AM To: MS-Exchange Admin Issues Subject: RE: Exch5.5 and Linux firewall >>your Linux Firewall or if you'd prefer, a firewall on a secure OS. -----Original Message----- From: Ellery July [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 30, 2001 6:16 AM To: MS-Exchange Admin Issues Subject: RE: Exch5.5 and Linux firewall Yes unless your smtp mail is coming in on a different port (which is very unlikely). Depending on your firewall I would have port 25 be able to go to that specific computer ipaddress. If you plan to run OWA you can still use SSL and port 443 with a Linux firewall. Not to get into an argument but MS Proxy is not really and firewall and your Linux Firewall will probably increase your security 90% or more. ellery july Technical Lead Northwest Area Foundation 332 Minnesota e-1201 St. Paul, MN 55101 email - [EMAIL PROTECTED] phone - 651-225-3895 fax - 651-225-7695 -----Original Message----- From: Fred Valdez [mailto:[EMAIL PROTECTED]] Sent: Monday, October 29, 2001 6:03 PM To: MS-Exchange Admin Issues Subject: Exch5.5 and Linux firewall Hello All, Does anyone have experience with exchange 5.5 behind a Linux firewall? I would like to use the firewall the same way ms proxy 2.0 is used. Basically, do I have to open port 25 on Linux and have it rout that traffic to exchange?... thanks, Fred Valdez GSRINC Network Administrator List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm List Charter and FAQ at: http://www.sunbelt-software.com/exchange_list_charter.htm
