SXT-LTE passthrough with the ability to manage

SOLVED (solution below)

I have a problem with configuring SXT LTE with RB3011. It’s about passthrough on eth1 for the internet and leaving management options on SXT LTE. I configured the vlans as described below, SXT gets the address from RB3011 DHCP but I can not get into its interface. Anyone can have an idea what could be a potential problem? Vlan is in a RB3011 lan bridge so … I’ve run out of ideas.

Solution
SXT:

  • set IP/Adresses interface from ether1 to local LAN SXT bridge
  • remove ether1 from LAN SXT bridge
  • create two vlan’s (1 for the internet and 2 for management), both connected to eth1 on SXT.
  • create Brigde_conf and add to it vlan_conf and ether1 on Bridge/Ports tab
  • set the DHCP client on bridge_conf
  • on the interface list, set WAN interface to vlan_net (1)
  • in Interface LTE/LTE APNs change the passtrough interface to vlan_net
  • disable firewall rule: defconf: drop all not coming from LAN

RB3011:

  • be sure that ether1 is not added on bridge ports tab
  • create two vlan’s as on SXT both supported under eth1 (SXT is on eth1)
  • on the interface list, set WAN interface to vlan_net (1)
  • add vlan_conf to lan bridge
  • create DHCP client with default route on vlan_net interface
  • add masquerade in Firewall/NAT: srcnat with vlan_net interface

Should work!

If your signal leds does not work add in system/leds:
add interface=lte1 leds=led1,led2,led3,led4,led5 modem-signal-treshold=-91 type=modem-signal
