RUTX11 - Wired WAN issues after 0.7.8.2 upgrade

[bigbloke]

Hi Guys

My “upstream” topology:

RUTX11-------LTE SIM1
|    |-------LTE SIM2 (disabled) 
|
|--WAN port -----WIFI TRAVEL ROUTER

WAN ethernet port has a static allocation x.x.x.254 with x.x.x.1 as the upstream gateway

Travel router has a static allocation of x.x.x.1

The concept behind the config is that when the vehicle gets parked underground, the LTE disappears but the in-office WIFI takes over

Since 0.7.8.2, I can no longer reach x.x.x.1 either by web interface or icmp

Nothing wrong with x.x.x.1 (verified by replacing x.x.x.254 with a laptop and it works flawlessly)

Despite having IPV6 disabled throughout the GUI, ifconfig shows me all the interfaces in V6 format. I rightly or wrongly assume therefore than interface wwan0 is my wired WAN ?

tcpdump -i wwan0 gets me:

09:49:01.071048 unknown ip 0
09:49:01.180759 unknown ip 0
09:49:01.181071 unknown ip 0
09:49:01.300736 unknown ip 0
09:49:01.301016 unknown ip 0
09:49:01.410710 unknown ip 0
09:49:01.410981 unknown ip 0
09:49:01.481946 unknown ip 0
09:49:01.520763 unknown ip 0
09:49:01.521019 unknown ip 0
09:49:01.630700 unknown ip 0
09:49:01.630971 unknown ip 0
^C
200 packets captured
202 packets received by filter
0 packets dropped by kernel

somewhat at a loss as to how to get this back now?

Any suggestions please ?

Hi bigbloke,

Wired wan interface is eth1 in ifconfig command. Is your RUTX11 LAN IP in x.x.x.x range? This might cause IP conflict in the network.

As per your use case, you can configure RUTX11 as Wi-Fi client and then enable Failover for Sim1(primary) and Wifi(secondary) reducing the devices overall.

Let me know if this helps.

Hi JanMiguel

Thanks for the clarification on eth1 I incorrectly assumed WWAN was “Wired Wan”.

The LAN interface and WAN interface addresses are separated by the 3rd octet

x.x.y.0/24
x.x.z.0/24

so no IP subnet clash

I understand that I can flip the config, but it doesn’t help me as my LAN contains both wired
and wireless devices I simply want to transition between cellular (primary) WAN and Wi-FI secondary WAN when cellular is not available and valid Wi-Fi is in range

prior to 0.7.8.2:

• cellular coverage lost
• failover detected and switch to Wired WAN (out to wifi bridge)
• service resumed as soon as upstream device enters wifi coverage

the WAN is set up as

X.X.Z.254/ (static IP) ----------------X.X.Z.1 (static IP) ////// wifi /////\ fixed internet

I can ping .254 from the X11 GUI , but cannot see .1

Ok , so ifconfig eth1 gives only a V6 address despite V6 being disabled throughout the
entirety of the X11 GUI !

so from the rutX11 CLI I perform ifconfig eth1 inet x.x.z.254

I now see a v4 address in ifconfig and I can ping x.x.z.1 again (cannot manage it from the VPN now - but that will be a separate issue !)

So for some reason the WAN parameters set in the GUI are not being parsed into the underlying OS.

Hi,

In you WAN configuration, can you add the Gateway IP as well? Then in Failover section, it should show that mobile is Online and wan is Standby. This is a clear indication that Failover will work.

the gateway is set correctly but the router is not routing ,

In parallel, I am seeing more and more errors (e.g. DHCP server issuing addresses in WAN subnet when that subnet is not even enabled for DHCP ?)

i fear the only way out of this is a factory reset and rebuild from scratch …ONCE AGAIN…

i really hoped we had got past that stage in product maturity but it seems not
