Hi together,
we have a W2008 R2 with actual patch level in a DMZ.
The Server is member of an internal domain (connectivity to AD is fine).
The server hat VPN (RRAS) and DHCP role to let external user connect.
The server is connected to internet with public IP 12.34.56.7 to witch the VPN clients should connect (having the default gayeway configured).
The server has also an interface to a V-LAN 23.45.67.8. This V-LAN is used to later route the clients to an internally protected network.
Within THIS network a DHCP range is configured 23.45.67.10-20. Client coming over 23.45.67.8 should get an ip address from this range and then route over the V-LAN.
Unfortunatly the RAS Service says: "EVENTID 20169 Unable to contact a DHCP server."
We put a client in the 12.34.56.7 and figured out that DHCP itself is working fine.
Only the local RRAS is unable to connect to the local DHCP. firewall is off!
Help is needed!
Greetings/Grüße Gernot
