I have a Linux server runnign behind a mr6400 v3.  The way I access my internal network is through ssh to my Linux server. 

If i want to access remote desktop or any other service I simply forward a port,  it works no problem for whatever services I need to access. 

When I try to access the router interface it does not work,  I have 2 tp link routers and both fail, but other brands work. 

Configuration:

mr6400 = 192.168.1.1

Linux server = 192.168.1.2

Steps to reproduce (remote host):

1. Connect over internet to Linux server through ssh 

2. forward local port 192.168.1.1:80 - > 127.0.0.1:8080

3. Displayed a partial login page (screenshot attached)

None of these links work

When I tried the same procedure on mr3020 I am shown a partial admin interface with message "you are not authorised to view this page" 

I think the 2 issues are related,  I know its to. do with the header showing the host ip as not being part of the local lan but I disabled firewall and allowed remote management in both cases and still have this problem. 

Is there any solution for this?  due to how my server is configured its not possible to connect using the external ip directly.
