one subnet not pingable

[Barry Cisna]

Hello All,

Peer2   (client) - Debian Bullseye
wwan0  = 100.64.2.161/30   # cellular modem CGNAT
bridge0 = ethernet & wifi interfaces   192.168.67.1
wg0client2  = 192.168.67.2

Peer 1 (server)
Google Cloud Instance Debian Bullseye static IPV4 address
ens4 = 10.128.0.2
wg0 +  192.168.69.1

PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A
POSTROUTING -o ens4 -j MASQUERADE
PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D
POSTROUTING -o ens4 -j MASQUERADE

Peer2, Clients connected to LAN/bridge0 both wired and wireless can
webbrowse but is delayed. DNS not exactly right,,

Peer2 can ping Peer1 fine responds both interface addresses

If Peer1 pings Peer2 at 192.168.67.1 returns "no message,,,something"
and returns 192.168.69.1
if Peer1 pings Peer2 at wwan0 it gets a response
So..it seems the wwan0 can not hop to the bridge0 interface for some reason,
I have tried for hours to make static routes what i think may work,and
always get "route already exists'. tried a few iptables guesses on
client,,,no go..

Thanks
