A little networking help, please

BrettZehr
I have nothing more than some basic networking knowledge, and could use some help. My XG box has 4 ports. I have ports 1 & 3 set as LAN and port 2 is WAN (port 4 is currently disabled).I have all the wired devices on port 1 with a starting IP of 192.168.1.1 and the wireless devices on port 3 attached to an AP with a starting IP of 192.168.0.1. I've put together some polices that allow the wired devices to access devices on the wireless network and vice versa, but I'm having trouble getting everything to work. For example, I have a Windows 10 laptop with an IP of 192.168.0.101 on the port 3 wireless network, and a Canon printer with an IP of 192.168.1.200 on the port 1 wired network. I can pull up the printer's configuration page on the laptop, but when I try to print, the laptop says the printer is offline. So what else do I need to do to allow the laptop on the wireless network to use the printer on the wired network. Or, is there a better way to separate the wired and wireless devices? Thanks.

    Zbrett,

    you can have both wireless and wired devices on the same network segment. It depends on what you want to achieve. You can, for example, have one wireless network bridged to LAN so they share the same IP, next have another Wireless network (separate) that your guest can use it and they do not have access to internal resources.

    Once you have decided what you would like to do, share your Policy rules, Zone and Wireless network and we will help you.

    Thanks.

    It became quickly apparent that putting the wired and wireless devices on different subnets created more problems than it potentially solved, so I moved everything back under the IP subnet range of 192.168.1.1 through 192.168.1.251. My XG box has been assigned 192.168.1.1 on port 1. 192.168.1.2 has been assigned to the AP. Right now I have nothing on port 3, I moved everything back to port 1. I guess what I need to figure out is how to get both ports 1 and 3 on the XG box on the same subnet..  That question has probably been asked and answered on the forum before, so I'll search around. Thanks.

    So would LAG be the best way to combine the nics on to the same subnet, or is there another, better way?

    Zbrett,

    I think that you are not using Sophos AP. If this is the case, create a bridge and put both nics that belong to the same network segment.

    You are correct in that I'm not using a Sophos AP. I am using this EnGenius ECB1750 AP. http://www.newegg.com/Product/Product.aspx?Item=N82E16833168138

    So pardon my ignorance, but how do I set up a bridge for the two nics. I got the impression I would have to have the Sophos box in bridge mode, and I need to use it as a gateway. 

    Thanks

    Zbrett,

    to create a bridge go to System> Network> Interfaces and select Add new bridge as show:

    As members add the ports where wired and wireless devices are connected. For both, select the same zone and give to a bridge an IP.

    That's all. For example if you create a bridge and choose the zone "LAN" what you have to do is to create a Lan to WAN policy rule allowing the needed traffic.

    Strange that there is not a Sophos KB on "How to create a Bridge".
