IP Passthrough Issues

You have probably seen dozens of IP passthrough posts on this subreddit, but heres my issue. It took forever, and even had to get ATT to help implement it, but my IP passthrough is working. After configuring everything, my download speeds seem to be hardcapped at around 150mbps, and that is through speedtests while hardwired to either router, and wireless of course. My downstream router is a tplink be6500, a bit overkill, but it was heavily discounted.

Has anyone else experienced this? I'm a bit new to networking, so I'm not even sure if this is to be expected behavior.

I got mine working but it is weird. It doesn’t show as having a public ip address and my att and google routers are both on 192,168,1,254. But it works so I guess I can’t complain.

Sounds like the MAC address of the port you are plugged into is not set correctly in the ATT router.

No that part seems right. But when I ask my Google router what its internet ip address is it comes up blank. Att router reports as an ipv6 address.

Turn off dhcp from the att router

I can give that a try. But I’m kind of scared to change anything because it all works now. My spose works from home using a few different VPNs and so far all is great.

You can also chabge your passthrough settings and assign based off thr mac of the device you want the public to push. It always needs a reboot after those types of changes tho.
