Hello,
We have a strange issue... We have DirectAccess single-NIC behind TMG 2010 setup and working over IPHTTPS. The client can ping internal servers, no problem. We have also setup selective ISATAP for several internal servers that we wanted to use for manage-out. Those servers have IP6 addresses and ISATAP appears to work and each server can ping each other over IP6 successfully. We have setup all the firewall rules needed for the clients to allow internal ping, file and printer sharing and remote desktop.
We can successfully ping DirectAccess clients and have tested all of the manage out functionality we need from the DirectAccess server, however we cannot ping or in any way access the clients from the other manage out servers we've configured. Any help is apprec
