Okay, I solved my issue by adding an iptable entry for the return from wlan0 to eth1 (BB).
* sudo iptables -A FORWARD -i wlan0 -o eth1 -j ACCEPT* Now pinging '8.8.8.8' from the BB works as expected. *root@beaglebone:~# ping -I usb0 8.8.8.8* *PING 8.8.8.8 (8.8.8.8) from 192.168.7.2 usb0: 56(84) bytes of data.* *64 bytes from 8.8.8.8 <http://8.8.8.8>: icmp_seq=1 ttl=103 time=17.9 ms* *64 bytes from 8.8.8.8 <http://8.8.8.8>: icmp_seq=2 ttl=103 time=15.8 ms* *64 bytes from 8.8.8.8 <http://8.8.8.8>: icmp_seq=3 ttl=103 time=15.3 ms* *64 bytes from 8.8.8.8 <http://8.8.8.8>: icmp_seq=4 ttl=103 time=15.7 m* Cheers, Jon On Sat, May 16, 2020 at 12:29 PM Robert Heller <hel...@deepsoft.com> wrote: > At Sat, 16 May 2020 13:32:03 -0400 beagleboard@googlegroups.com wrote: > > > > > Jon, > > > > So you can ssh from the PC to the BB and ssh to the PC from the BB... > > > > So the two are talking.
