17.7 Legacy Series / Re: OPNsense behind ISP router with NAT

Thank you very much. This is what I thought. I do not think my ISP supplied router allows the addition of routes -
 have looked and have searched. So will stay with double-NAT. Resigned to the fact that if I need to alter this looks like I will have to upgrade the ISP-supplied ADSL router/modem device to something a bit more sophisticated. Peter

17.7 Legacy Series / OPNsense behind ISP router with NAT

« on: December 31, 2017, 06:35:54 pm »

I have struggled to get my head around OPNsense which I am looking at for routing between subnets and controlling access to Internet.

I have eventually got a subnet on the inside accessing the internet and to another inside subnet.

Now I want to remove the NAT going out to the WAN since the WAN connects to an ISP router also doing NAT. So I turn off outbound NAT.

I now cannot get to the Internet. I cannot ping the ISP router.

I was wondering whether issue is routing so added RIP for all subnets. Do I have to manually add a route onto the ISP router to say go to my OPNsense box for the following subnets ... . Or is it something else I am doing? Any help or examples or documents explaining this process would be welcomed.

Thank you,
Peter
