No NAT
Posted: Wed Oct 19, 2016 11:56 pm
I bought a Billion 8800NL R2 to a few days ago via Amazon to simply connect via PPPoE over FTTC and pass through external IP addresses to the "real" router. I get a block of 16 from my ISP. I followed this: http://www.billion.uk.com/edu/VDSL2/index.html - "If you have multiple WAN IPs / block of public IPs".
My allocation is 78.33.192.48/28 from my ISP and 78.33.192.49 is given out via DHCP when requested.
Steps to reproduce:
* Factory rest Billion router
* I gave the Billion my ISP user/pass and it got 78.33.192.49 on WAN. I was able to browse the internet
* I then unchecked the NAT box on WAN and restarted it.
* My laptop is plugged into a LAN port on the Billion and I gave it an IP address of 78.33.192.60/29 with a default gateway of 78.33.192.49
Expected outcome:
* Internet access
Actual outcome:
* I could not access anything externally from my laptop.
* I could connect to the default RFC1918 address on the router - 192.168.1.254. I did not expect that.
Where am I going wrong?
Cheers
