It's not your router per se. It may be the DNS server you are using or a problem with your browser. 

Site works fine for me after having to look up the link (spelling mistake and all) because you did not provide it. 

Thanks for the reponse.

I feel like I've ruled out a browser issue as I have tried multiple browsers on my desktop and I have tried the browser on my ipad and iphone and could not access the website on any of the above.  All of them connected to my router (destop hardwired and Ipad & Iphone via wifi).  Also I tried turning the wifi off, so that it was using my cell phone plans internet access instead of through my router, on my Iphone and it did access the website normally.  I then turned the Iphone wifi back on and again was not able to access the web site.

I also suspect its a DNS server issue.  I did try setting up OpenDNS on my computer to test the DNS theory, but still could not access the website.  I'm not sure though if I set it up correctly (I don't know to much about DNS) or if it doesn't matter setting it up on my computer, because I'm still going through my router.  Would I need to set up open DNS on my router to properly test if its a DNS issue?  Is there any downside to setting up my router with Open DNS?  Also not quite sure how to setup something like Open DNS on my router?

In the advanced network tab of your router setup, temporarily change the Primary DNS server to 8.8.8.8 (Google's public server) and re-try.

If it works, the DNS cache of your original DNS server is probably corrupt.

The Router has a stateful packet inspection firewall, but this should not be blocking access.  If you have enabled access control or parental controls and do not have the site on the black/white list that could be the cause.  Also another cause could be the ISP itself is blocking the site.  They have been know to do that in the past for a site that doesn't pass their inspection.  If your modem is a gateway and is operating as a router then the issue could be double NAT.  Please check these items and let us know.

I checked and I don't have access or parental controls enabled.

I don't know how to check if my modem is a gateway or operating as a router?  I get my internet through the local cable tv provider.  The cable connects to a modem that the cable tv provider installed.  The modem is connected to my router via an ethernet cable.

Also I contacted my cable tv internet provider and they confirmed that they could access the web site from their end.  I will try connecting a laptop up directly to the cable modem later to see if I can access the web site that way.

Same problem with my router too, cant access samsung.com, when i tried connecting directly from modem it works, Router is blocking this site dont know why

Disconnect from any VPN you might be using. Some sites will reject a connection thru known VPN IP addresses.

I just connected to the Apollo Journal and Samsung sites thru my C9 V1. The Samsung site automatically re-directed me to their Canadian site because they picked up my ISP's location. Switching to a European VPN, Samsung connected me to their Netherlands site.

In both cases, typing in Apollo Lunar Surface Journal brought up a search engine page first with the real site name.

I don't believe I have any VPN setup.  I weas able to access the website by connecting my laptop up directly to my modem.  So it would seem, based on all the testing I have done, that for some reason it is my router blocking access to that web site.  I just can't figure out why or how to correct it.  Unless someone has a idea, I guess I will set everything to factory default settings on my router to see if that fixes the issue.
