From the perspective of the Lync Server on forest A and Exchange UM server in forest B
What firewall ports need to be open from the server perspective?
Specifically does the Lync UM server need to be able to talk to the DCs in forest B directly ( and similarly Exchange UM server to the DCs in forest A)?
Ports such as
Port | Protocol |
135 (TCP) | RPC End Point |
389 (TCP) | LDAP |
3268 | LDAP |
88 (TCP) | Kerberos |
445 (TCP) | Microsoft-DS Service |
Any advice much appreciated
Regards
Alistair
