    Dear Tmg Support Team,

    We are not able to implement Tmg server as a transparent proxy in a multiple  Vlans, what configuration should i give to internal NIC as well to external NIC.

    when we are  assinging default gateway 10.100.10.2 to external nic internet is not working  (as we want the traffic to be out through firewall)

    With lack of detail here, I cannot give more than general advice.

    Ext IF - has default gateway (on the same network as the Ext IF IP address). NO DNS configured.

    I

    TMG

    I

    Int IF - has NO default gateway, only static routes for internal networks. Has DNS configured pointing to an internal DNS that either can resolve names by itself of forwards requests to another DNS server. If needed TMG has to be configured with an access rule to cater for this.

    Hi,

    Thank you for the post.

    Besides Anders said,  you should add the subnets to the Internal network on your TMG Server.

     firwall

    ip add 10.100.16.2

    subnet 255.255.255.0

    default gateway 10.100.16.254

    tmg server

    ip add 10.100.17.6 255.255.255.0

    subnet 255.255.255.0

    default gateway 10.100.17.254

    Both TMG and Firewall are connected through Core Switch and both the vlan's (10.100.16.0 & 10.100.17.0)are interconnected.Our internet traffic is going out from Firewall. We are diverting the traffic to TMG server IP address. But when we are assigning default gateway to TMG as 10.100.16.2 internet is not working in TMG

    Hi,

    Thank you for the post.

    “But when we are assigning default gateway to TMG as 10.100.16.2 internet is not working in TMG ” – the default gateway on TMG server should point to your core switch ip that direct connect the TMG server. And you should configure route and ACL on your core switch.
