So, for ar71xx generic om2p, I’m able to set up an AP/router with IP 225.1.2.1:

root at uniextap:~# ip addr show br-lan
8: br-lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether ac:86:74:10:26:30 brd ff:ff:ff:ff:ff:ff
    inet 225.1.2.1/24 brd 225.1.2.255 scope global br-lan
       valid_lft forever preferred_lft forever

and pick up a DHCP address in that subnet from an STA:

root at uniextsta:~# ip addr show wlan0
5: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000
    link/ether ac:86:74:03:0d:f2 brd ff:ff:ff:ff:ff:ff
    inet 225.1.2.120/24 brd 225.1.2.255 scope global wlan0
       valid_lft forever preferred_lft forever
    inet6 fe80::ae86:74ff:fe03:df2/64 scope link 
       valid_lft forever preferred_lft forever

and NAT traffic on that subnet to the Internet:

root at uniextsta:~# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
64 bytes from 8.8.8.8: seq=0 ttl=56 time=11.562 ms
64 bytes from 8.8.8.8: seq=1 ttl=56 time=12.722 ms

root at uniextap:~# tcpdump -i eth1 icmp
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 262144 bytes
18:50:32.290616 IP uniextap.lan > google-public-dns-a.google.com: ICMP echo request, id 1252, seq 0, length 64
18:50:32.300259 IP google-public-dns-a.google.com > 10.72.0.37: ICMP echo reply, id 1252, seq 0, length 64
18:50:33.291222 IP uniextap.lan > google-public-dns-a.google.com: ICMP echo request, id 1252, seq 1, length 64
18:50:33.302339 IP google-public-dns-a.google.com > 10.72.0.37: ICMP echo reply, id 1252, seq 1, length 64

Tires kicked. Anything else?
