ipv4+ipv6 on Chateau 12 LTE / Quectel EG12

RouterOS RouterOS beta

Dear all,

I’m new to Mikrotik routers and have just received my Chateau 12. I have a strange home setup where I have 2 gateways on the same LAN, one is a 4Mb/s ADSL line which offers both ipv4 and ipv6. I cannot deactivate ipv6. I have a small bandwidth but a lot of services on the ADSL box so I don’t want to get rid of the box either. The second gateway is the chateau 12. The LTE interface seems to offer ipv4 xor ipv6 but I could not find ipv4v6 in the LTE APN menu. With Chateau

  • In ipv4 mode only, all ipv6 traffic gets routed to the (slow) ADSL interface => slow
  • In ipv6 mode only, all ipv4 websites fail.

Ideally, I would like to have the LTE interface in IPV4V6 mode but I do not see it on my LTE APN interface. My provider claims it supports ipv6 (and the chateau does work in ipv6 mode), it also supports IPV4. I tried:

at-chat lte1 input="AT+CGDCONT=\?"  
  output: +CGDCONT: (1-42),"IP",,,(0-3),(0-4),(0-1),(0-1) +CGDCONT: (1-42),"PPP",,,(0-3),(0-4),(0-1),(0-1) +CGDCONT: (1-42),"IPV6",,,(0-3),(0-4),(0-1),(0-1) +CGDCONT: (1-42),"IPV4V6",,,(0-3),(0-4),(0-1),(0-1)

and it seems that the EG12 is IPV4V6 capable. Also:

at-chat lte1 input="AT+CGDCONT\?"  
  output: +CGDCONT: 1,"IPV6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0 +CGDCONT: 2,"IPV4V6","ims","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0 +CGDCONT: 3,"IPV4V6","sos","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0, 
          0,1 +CGDCONT: 4,"IP","","0.0.0.0",0,0,0,0 +CGDCONT: 5,"IP","free","0.0.0.0",0,0,0,0 OK

seems to show that ipv4v6 is possible on “ims” and “sos” PDP.

Does anyone know if there is anything I can do to get ipv4v6 working on chateau 12 ?

I having the same issues. Would love any ideas to fix.

Hello Loneranger,

Did you contact Mikrotik support as suggested below? If yes, did you get an answer?

Well. I contacted them and got the solution (or more precisely, the beginning of a new adventure as I now get 2 IPV6 gateways on my LAN and this creates IPV6 chaos):

You should use dual APN functionality. Please create two separate APNs - one for IPv4 and the other for IPv6. Then assign both APNs to your LTE interface, for example, /interface/lte/set lte1 apn-profiles=ipv4,ipv6. You should see IPv4 address under /ip/address/print and IPv6 under /ipv6/address/print.

Any one have any luck with this? Im on AT&T with a EG12 modem. I got the v6 subinterface to go up once, but it didnt pull an address. I had IPv6 interface set to none, so I tried setting it to lte1 and lte1.v6 subinterface, but could never get the v6 sub interface to go up again after that.

I get this in the log

lte1 mbim: error: >>> E service: connect, command: connect, error: 2


Any ideas anyone? thx.

Edit, the subinterface went up after a while, but still no v6 address appearing anywhere.
