PA-200 with 4G LTE modem

ChrisDownes — Wed, 18 Mar 2020 22:39:29 GMT

I've got a PA-200 at home with a Huawei B525-23a router set to "bridge mode" with an EE data sim installed (no broadband where I live)

The outside interface is set to DHCP and gets an IP address but no clients on the inside can resolve DNS. I can see the logs showing that DNS requests have 'aged-out' but think that's expected for UDP DNS queries.

I've tried setting the inside clients to use google for DNS via DHCP and enabling DNS proxy with the PA-220 inside interface as the DNS but neither work.

I also have a Meraki MX64 and with this connected all works ok and the WAN interface has an IP address of 19.7.44.xxx , G/W of 19.0.0.1 and a public IP of 213.205.192.xxx

The PA-200 gets an outside DHCP address of 19.7.44.xxx and G/W of 19.0.0.1 but doesn't seem to recognise that is behind a CGNAT so I assume the return traffic is getting lost.

Any ideas?

Hello,

Are both 4g routers hooked up at the same time or are you looking to migrate from one to another? Also are you looking at a failover scenario where if one fails it goes to the other?

Please advise,

There's only one 4G router (the Huawei) There is no other WAN to failover (I have no broadband here hence the 4G)

I was using the Meraki and then switched over to the PA-220
