Hi,

I get in trouble with TMG MBE on EBS.
When I configure or reconfigure any rules and I apply it, communication beetwen internal and external is donw because the default gateway in internal NIC is configured on 0.0.0.0
Any idea why I have this trouble ?

Regards.
GG.

The security server, like most versions of windows, can only have one default gateway.Not one default gateway per NIC, but one default gateway. So this sounds like a normal configuration to me. How have you decided that the default gateway is the issue?

During the installation of EBS we confiure one NIC for external access and one NIC for internal access.
The normal result of ipconfig is :
C:\>ipconfig

Configuration IP de Windows


Carte Ethernet Connexion au reseau Internet :

   Suffixe DNS propre à la connexion. . . :
   Adresse IPv4. . . . . . . . . . . : 192.168.169.20
   Masque de sous-réseau. . . . . . . . . : 255.255.255.0
   Passerelle par défaut. . . . . . . . . : 192.168.169.10

Carte Ethernet Connexion au reseau local :

   Suffixe DNS propre à la connexion. . . :
   Adresse IPv4. . . . . . . . . . . : 192.168.168.1
   Masque de sous-réseau. . . . . . . . . : 255.255.255.0
   Passerelle par défaut. . . . . . . . . :

No default gateway on my local network
Now when I modify any rule and I valid the modification on TMG I get this result of ipconfig
C:\>ipconfig

Manually we cannot type manually 0.0.0.0 on the field of default gateway. :(

Looks like your metadata got corrupted in the EBS store in AD. EBS checks this whenever TMG syncs, so this is actually an EBS issue. Log into the security servr and run the "Change IP Address"wizard (an EBS specific tool) and enter all of the appropriate data. This will write new data to the EBS store and fix the problem.

Hi,

This the good way, I did it, but first it was not working properly because we change Administrator account password and we do not chnage it in SCE. After changing using console of SCE the new configuration was saved on AD.
Thank you very much.
