How to fix gateway problem?

Mike, you cannot have 2 different gateway with same ip.

Make sure they use different IP.

Regards

The gateway is not my main router?

Mike,

please upload a network diagram.

You cannot have 2 identical ip for 2 different objects using for routing.

Thanks

I have a router 192.168.110.1/16

static ips 192.168.110.2-254

dhcp 192.168.111.1-149

Im using XG Firewall as bridge with the static IP 192.168.110.3, DHCP relay for br0.

All works good with this, i also have 2 firewall rules, the first for the segment 192.168.110.2-254 that has social network, etc. and the second one 192.168.111.1-254 that hasnt social network, p2p, torrents, etc.

What i want to do is use the segment 192.168.111.150-254 for WIFI (tp-link aps), so i have a working rule for that ip range to ask for username and password by the captive portal, BUT, i have done the bridge i showed in the first post, so, my router (192.168.110.1) is giving dhcp from 111.1 to 111.149, and i want to give dhcp with sophos in the rest of the ip (111.150 to 111.254), but i think that is my mistake.

The sophos server (Dell PowerEdge T310) has 2 network cards (gigabit), the first on the board for port 1 (wan) and port 2 (lan) used in the first bridge (192.168.110.3), the second card has the port 3 (wan) and port 4 (lan) for the second bridge (192.168.110.4), im trying to add the dhcp service for bridge 2, with the range 192.168.111.150 to 254, and works, but without internet.

:/

What should be my best way to do this? sorry :(

Can you upload a network diagram?  You can download a free trial

I actually bought it trying to explain my network diagram to different people.

I have a xg  home appliance but i have been more focused on my xg 310 appliance at work...

I dont know if this help, i hope yes, thanks for all your time and help :)

I need to try to draw a network diagram like this one.  I confuse everyone with my diagrams.

Thanks Mike for the great network diagram.

You are able to ping 8.8.8.8 but XG does not resolve DNS names (even from console)?

What DNS your XG are using? Check them inside Network > DNS and let us know. What DNS are your internal computers using?

If they are using external DNS, make sure an allow DNS rule exists.

I can do this, but i would like to show you my settings, im attaching the firewall rules, bridges, gateways and there are a red dot on gateways, i dont know what to do :S

Thanks for the help.

Mike,

send me a PM and I will have a look at your XG.

I adviced Mike to use XG in routing mode, by

• removing all the configured bridge
• using VLAN on LAN physical port (router on the stick)
• Removing even the Tplink router and connecting the 2 ISP interfaces to 2 differente XG physical ports
• Using XG DHCP server on VLAN

additional to the case:

thanks for all your help. I was able to make it work, what i did was to erase my second bridge as you suggested, and use one of my available ports into my first bridge but in the wifi zone, then i create a new firewall rule for source wifi zone with captive portal, so it worked :)

thanks a lot!

Hi Mike ,

We are Glad you were able to resolve the issue , Just a Note to add and apologies for the delay . If your WAN interface has 1 Gateway with the same device the MAC host is constant factor and on XG you you cannot use two interface that would point to the same Gateway . In this case only one will be active and another will not be active . Also the Arp entry would also be affected on the Router on the WAN interface . Our recommendation you may use a Single interface an if you have multiple addresses you may add a Alias .
