Hard Crash With iptable Entries AC86U 384.8 alpha

P.S. @john9527 The TEE is only in your test load not available in RMerlin's 8_2

It's there, but you have to modprobe the module on Merlin's build

Well, since I've had other issue with the newer loads, I'll just stay with your test load. Plus, it's easier for trying to get the mirroring to work, and if successful, not have to modprobe in the event of a reboot.

It looks like this change never made it into your mainline code?

# CONFIG_NETFILTER_XT_TARGET_TEE is not set

Hmmm.....it's there now

I finally decided to be happy with what is possible.
I connected the 2nd NIC in the machine and assigned it an IP. Made some changes to the Apache ports so it wouldn't look at the mirrored traffic. Presto! I have what I've been working for. The weather station data goes to the weewx server and also reaches its other destinations on the Internet.
I do have a problem with this.
First, unless and until TEE is built into another load, I am frozen with @john9527 test load. Not a huge deal for me.
Second, where oh where can I find some good info on dual nics with the same subnet on one Linux machine? The default route is not, of course, not the 'main' IP (.115). Which does raise issues with a few things. Luckily, not the Apache server.

Here's what I have done in the router (scripts/firewall-start). Thanks for all the assistance and patience guys!
