Setup OWA on exchange 5.5

[sofiabpm]

Hello,
I need help for setting up my network with OWA.
1. Exchange 5.5 - behind firewall
2. Web service is provided by the ISP
3. Firewall port 80 is open
4. We have separate domain name with MX record registered with verisign.
Few months ago I open the access trough the firewall for pop3 access, then I got flooded with Spam mail and I was caution to close the open relay. Then I close it but I couldn’t find any good solution for opening it again that's why I decided to try OWA. With one word tell me how to do that configuration. I have installed HTTP connector but is not configured yet.
Thanks in advance

You should put OWA on a separate server and allow ONLY port 80 traffic through the firewall for this server. Ideally, you should put the OWA server on a third NIC (or DMZ) of the firewall. Unfortunately, I don't know how to tell you to do this. Perhaps someone else on this forum can help...
