Issue with an ERL behind a CradlePoint MBR1400
-
I am having the damnedest time getting an ERL to work correctly behind a CradlePoint MBR1400.
The CradlePoint is in IP Passthrough mode and the ERL is getting the correct IP address.
I posted the details over on the UBNT forums, but wanted a different set of eyes to poke on it too.

Silly question, but I've seen the term ERL used a lot on ML lately. What is an ERL?
-
@thanksajdotcom From the context it looks like it stands for Edge Router Lite.
-
Yup, The Edge Router Lite the former entry point into the enterprise firewall and routing space from Ubiquiti.
-
Remove the static route. I assume that's there to force all traffic out via eth0, right? I assume the ERL has a WAN port, right?
-
Ok, never mind. No WAN port. Looked it up.

Not sure if I'm misunderstanding something, but I noticed a discrepancy in your post on Ubiquiti's site. In the interface list in the GUI, eth0's IP ends in .52 but at the CLI it shows it as ending in .53. Is this how it's supposed to be?

eth0 is DHCP assigned from his configuration.

eth0 is DHCP assigned from his configuration.
That's why I'm wondering where the discrepancy comes from.
-
Never mind. I just did the math. The .52/30 is the network address. .53 and .54 would fall inside that subnet.

Have you tried hard setting the duplex & speeds and also maybe try a cross-over cable between them.

Most modern networking devices don't care about the pattern of the wires, as long as it's consistent. They can make almost anything work.

Auto MDI-X and Auto negotiation doesn't always work which is where you can see odd problems like this.

Picked this back up tonight. new information in the UBNT forum, but looking at MTU issues now.
Trying one more setting then calling it a night.

I have to change my mtu to 1350 I think on 3G. I've seen TCP Window scaling cause similar issues as well (and along with) MTU issues, But I would hope never devices would have issues with it as they both seem to be new enough.
