TRB140: how to enable remote (WAN) WebUI from ssh access

[gkovacs9999]

Hello,

I have a TRB140. Is it possible to enable remote (4G) WebUI from ssh access? Before deployment, I forgot to enable WebUI access from 4G, is ot possible to enable it from SSH (luckily I have enabled that).

For those who stumble here, this is the solution:

1. First you need to allow the server to be accesed from the wan port:

uci set uhttpd.main._httpWanAccess='1'
uci commit uhttpd

2. You need to restart the www server of the router:

/etc/init.d/uhttpd restart

3. You need to find the firewall rule that controls access to port 80 from WAN:

uci show | grep fire | grep "'80'"

response:

firewall.16.dest_port='80'

4. If you got this as reponse, let’s check the complete rule:

uci show | grep firewall.16 

and you got this response:

firewall.16=rule
firewall.16.dest_port='80'
firewall.16.proto='tcp'
firewall.16.name='Enable_HTTP_WAN'
firewall.16.target='ACCEPT'
firewall.16.src='wan'
firewall.16.enabled='0'

5. The last line tells you that the firewall rule is disabled (essentially the route is banned), so let’s enable it:

uci set firewall.16.enabled='1'
uci commit firewall

6. We have to restart the firewall:

/etc/init.d/firewall restart

And that’s it!

Note: this solution may work for all RUT-s and TRB-s, as long as you fine the correct firewall rule…
