Huawei B818 Bridged Mode
-
Hey, I have a Huawei B818 I have put into bridged mode and am attempting to connect pfSense to my Mobile Broadband connection with 2degrees (NZ).
With the B818 in bridged mode, Ive tried DHCP and PPP modes to authenticate and get a active connection, but neither works. Is there something im missing?
Thanks

Depends how your provider is expecting the connection.
In DHCP mode does the interface get an IP address?
In PPP mode do the logs show it successfully connecting?

@stephenw10 no neither seem to be working at all, in DHCP mode the interface just stays down.
PPP just fails to connect.

Hmm, it's an external 4G router so I'd expect bridged mode to offer DHCP. This post seems to confirm that.
Looks like you need to be sure DHCP is enabled before you put it in bridge mode though.Steve

@stephenw10 but wait, doesn't DHCP get offered by my ISP in bridged mode. As in DHCP WAN IP is offered then I would see my WAN IP on the pfSense WAN interface?
Thanks
-
Yes, it should pass the ISP supplied IP to the pfSense WAN. Or at least that's what I would expect to see.

@stephenw10 as in the LAN DHCP server?
-
Ok so DHCP was enabled the whole time but I went to my ETHERNET settings (I think this meaning ethernet WAN port) and set to LAN Only and now its working.
However, the device is still reachable via the private ip. This does make me wonder if this is a true transparent bridge. I dont like this.
-
Are you seeing the public IP passed to the pfSense WAN?
-
@stephenw10 yes, after making sure the LAN DHCP server was enabled and setting the WAN/LAN mode the LAN Only, now pfSense is getting a my static private IP, however somehow I am still able to ping the router @ 192.168.1.1 with no gateways and static routes in place

@deanfourie said in Huawei B818 Bridged Mode:
pfSense is getting a my static private IP,
You mean public IP?
Well the LTE router is in the default route so it will be able to respond as long as it has a route back to the pfSense WAN IP, which it apparently does.

@stephenw10 sorry Public IP, I should go back to bed.
But in bridged mode, I would not expect there to be a route.
After all, it should be a transparent device no?
-
Check the MAC addresses. Does the 192.168.1.1 IP appear to use the same MAC as the gateway?

This post is deleted! -
I mean the upstream gateway that pfSense is using on the WAN side. Which I imagine must be one of those 163. IPs? And I assume that's inside the WAN subnet?
You would have to open a request to 192.168.1.1 and if it's local you might see it.
However given that you can see at least 4 IP in the 163.47.0 subnet they might simply be routing that to you. In which case 192.168.1.1 might just be added as a second IP on the router. pfSense would not see that as local but can still reach it via the default route.

@stephenw10 but why on 3 different subnets, I'm assuming they are /24 and there is a .0 .1 and .2 subnet
-
What size WAN subnet does it give you?
The fact you are seeing those IPs in the ARP table implies they are sending traffic to you. So probably broadcasts.
-
@stephenw10 so why would I be receiving traffic on another public IP other then my own static public IP?
Is this normal?
