Regarding smf2s's difficulty in setting a default route, I looked for strings in the busybox executable,
and saw:
[[ip route add default via %gateway% dev %iface%]]
Then I crossed my fingers and typed something like
ip route add default via 192.168.1.254 dev br0
and got with no complaint. Then
~
# ip route show
192.168.2.0/24 dev br1 proto kernel scope link src 192.168.2.1
192.168.1.0/24 dev br0 proto kernel scope link src 192.168.1.3
default via 192.168.1.254 dev br0
I wonder, cluelessly, what I am missing to ping or traceroute 8.8.8.8?
I can't say I'm gagging to learn about running tcpdump on my router.
Should I disable the firewall?
I can still ping the router at 192.168.1.254 and other 192.168.1.* addresses.
