Why can't clients see the network when connected via OpenVPN?

Question

linux

Good afternoon!
Tell me please, how can this be?
There is an OpenVPN server, clients connect using certificates, but they don’t see the rest of the network, if I turn off iptables - they start to see, I allow everything in iptables - it doesn’t work))

Answer 1

Maybe it's the standard OPEN VPN port 1194, you can't say that right away. Poke around in the rules. And what's in the client and server configs?

Answer 2

show
cat /proc/sys/net/ipv4/ip_forward
and iptables-save
