Internal to internal access

Sunghwan Yoo

Hi all

Public IP: 120.1.1.1

Internal server IP: 192.168.0.192

I can access to 192.168.0.192 from external network via http://120.1.1.1 with port forwarding

But is it available to access from internal network(192.168.0.0) to 192.168.0.192 via http://120.1.1.1 ?

If I understand correctly you want to access 192.168.0.192 using its public address of 120.1.1.1 from the 192.168.0.0. network, I don't know why you would want to do this, is it something to do with DNS only resolving to public address?

Hi

Your understanding is correct.

Because, I am using mobile device connected to DVR  from inside or outside of office.

So I want to monitor my office wherever I go.

If I configure internal IP(192.168.0.192:2200) on mobile device, it is only working in the office.

and if I configure public IP(120.1.1.1:2200), I cannot use in the office.

That's why I am trying to solve this problem.

also I don't have DNS server.

when I used other SOHO router(TP-LINK), it was working fine without any configuration.

How can I solve this problem?

Are you trying to connect to 120.1.1.1:2200 from public internet and get it forwarded to 192.168.0.192:2200?

Do you have a NAT configuration?
