Access internal IPs from vpnclient

Post by redscream » Fri Nov 13, 2020 9:47 pm

Dear all,

I am using Softether VPN server I have a question. I appreciate if you could help me.
I use local bridge and I would like to access to the servers internal IPs from vpn client. Let me give you some details.
This is my ifconfig output.

tap_soft Link encap:Ethernet HWaddr 00:ac:79:c7:20:30

Client gets 192.168.7.50 IP adress from softether, I can ping from 192.168.7.50 to 10.0.0.1 but can not access to 10.0.0.110, 10.0.0.111, 10.0.0.112. These Ips are pptp VPN ips of other pptp clients. I am running both softether and native pptp vpn servers on my server.

Thanks in advance

I think you have too strickt mask at the client, what is it? 255.255.255.0?

What should be the netmask to access 10.0.0.x network from 192.7.1.X ?
Thanks

0.0.0.0

but it will probably affect whole network (other things would probably be not working)

yes I did it the VPN clients could not connect, is there any other way to configure it?

make both subnets closer to each other 10..... and 192...... are too different

both either 10 or 192

use this calculator http://jodies.de/ipcalc and you will see if you can reach other subnet
