Hi,

My ISA2004 connect to 2 networks,
In the 2 network we have a DHCP server, the isa behave like a dhcp relay agent i try to disable it in the "System policy" but the rule didn't remove.

Any help?

Thanks

Have you restarted the Firewall service ?

Kind regards,

Hi Shaul,

Did you install the DHCP relay service on the firewall? By default, the ISA firewall blocks DHCP messages and does not pass them across networks. Are all the interfaces on physically separate networks?

Thanks!
Tom

Hi Shaul,

In that case, it could be that the two networks are physically connected by means outside of the ISA firewall.

HTH,
Tom
