OWA (Exchange 5.5 on Win2K server) was working fine until I changed DSL lines. I have good e-mail in and out, but cannot access OWA from outside. I use simple SMC Barricade firewall with one IP address and 192....... addresses doled out within. I can access OWA properly from within if I use browser to inside IP address/exchange, but not by using mail.domain.com/exchange as I did before, inside and out. Is this some DNS setting I must make inside? I do not at this time run DNS inside.
