Client has small NT network with 1 SBS 2011 server as AD, FS, everything (Exchange disabled - use Office 365 now). Remote employees access the Shared files thru
https://mail.xxxxxx.com/remote. Upgraded firewall from a Sonicwall TZ105 to a Draytek 2960. I have opened ports 443, 987 and 1723 and we still can not get into the Remote Web Access. What step am I missing? Thx for your help.
