Re: [lime-users] setting one mesh device as gateway? (and nanostation M2 update)

Pau, Thanks for the info. It appears that you can do this through the UI. I tried adding the lines as per the doc to /etc/config/lime, then ran lime-config but it didn't seem to make any difference - eth1 was still shown as being in wan. I then made the change through the UI - added eth0 to wan instead of eth1, and it then got DHCP ok. But, no devices connecting to the mesh networking could route out through that connection (their gateways were set correctly to 10.13.0.1, all mesh devices were talking to each other, and the mesh device with the gateway could connect to internet devices fine) So, I tried adding manual NAT settings [1], and this made everything work! Is that the correct way to set up the gateway device, or is there a setting somewhere in the libremesh firmware that should have taken care of this for me? Thanks again James [1] (obviously with interface names changed) iptables -A FORWARD -i wlan1 -o wlan0 -j ACCEPT iptables -A FORWARD -i wlan0 -o wlan1 -m state --state ESTABLISHED,RELATED \ -j ACCEPT iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE On Tue, Mar 28, 2017 at 8:08 PM, Pau <pau(a)dabax.net> wrote: > On 28/03/17 18:54, Ilario Gelmetti wrote: >> On 03/28/2017 06:41 PM, James Lewis wrote: >>>>> On 28/03/17 16:13, James Lewis wrote: >>>>>> Now the quesiton is: how do we set one of the mesh devices to _take_ >>>>>> DHCP through the LAN port rather than give it, and to be the 'gateway' >>>>>> device on the mesh network, and then what will happen with devices >>>>>> that subsequently connect to the mesh?
