Hi,

I'd like to configure my USG40 in this scenario:

IP Router 192.168.1.1

Ethernet configuration inside USG40:

WAN1 192.168.1.240 - SUBNET 255.255.255.0 - GATEWAY 192.168.1.1

LAN1 192.168.1.241 SUBNET 255.255.255.0

DHCP NONE

LAN2 - DMZ - OPT....NONE

inside USG40 configuration I put above values and inside SECURITY POLICY->POLICY CONTROL leave default values (there are 15 default rules).

connection:

Rotuer cable to WAN P1 USG40

LAN P2 TO SWITCH

configuration PC

192.168.1.10 - 255.255.255.0 - Gateway 192.168.1.241

ok connection between pc and USG (ok ping 192.168.1.241) but pc dont goes to internet.

Any help?

thank you.

Damiano

    Can you make the WAN1 get the WAN IP and not by another NAT router?

    Maybe you need to bridge WAN1 and LAN1 in your scenario

    Having 192.168.1.xxx on WAN1 and LAN1 with the same subnet is whats causing your problem.


    Another way is to use static routes on your ISP router? with its IP/subnet to 192.168.1.1/255.255.255.0 with a static route of destination IP 192.168.2.0 subnet 255.255.255.0 gateway IP 192.168.255.254

    Then on the USG40 WAN1 gateway 192.168.1.1 IP 192.168.255.254 subnet 255.255.255.0 - LAN1 IP 192.168.2.1 subnet 255.255.255.0

    PC in 192.168.2.2-254 gateway 192.168.2.1 subnet 255.255.255.0

    now add a policy route with:

    incoming Interface

    member LAN1

    next hop

    type Gateway

    gateway make address for 192.168.1.1

    Address Translation

    source network address translation none


    And I think that should work.

    Hi @PeterUK thank you fo help.

    The problem is that ISP router is locked. The internet company installed a router that do not give to me access. When I nedd to open ports or any other I have to call them.

    Bye

    Your options are limited you can't forward ports on your ISP router then with the USG40 can't either. So your option is to bridge WAN1 and DMZ to control traffic and you can set br0 to 192.168.1.254 make a zone br0 and set in for br0 and make a policy control to allow from br0 to ZyWALL so you can login to the UGS40.

    WAN and DMZ are bridged so the IP's in WAN and DMZ are not needed unless by setting WAN to 192.168.1.1 is so change it to 127.255.255.2.
