Outbound Network Requests Failing


Hi, for while now dnf has been failing when I run the update and install. At first I thought the servers may be busy, per a couple of a forum responses. After a bit I started digging deeper into what looks like a network issue on my end as outbound requests fail at the router. I assuming this because nslookup is all that is working, and it is only communicating with the router.

Network Setup:
192.168.100.1 - D-Link DSR-150 Router
192.168.100.2 - Fedora 23
192.168.100.3 - Fedora 23
192.168.100.4 - Wifi Router (clients working fine)
192.168.100.5 - Windows 7

D-Link is configured to forward 80 & 443 to 192.180.100.2. Default Outbound Policy for IPv4 & IPv6 are both set to allow.

Both Fedora boxes are set up exactly the same, so they're both having the same issues. One Fedora box is set up to server DNS & Samba, the other serves HTTP & HTTPS. From Fedora, I can ping LAN IP's no problem, but can't ping anything outside of the 192.168.100.* range. From Windows I can ping anything/anywhere, no issues (using it to write this post). In bound requests to HTTP & HTTPS are working fine. Any help would be appreciated, I can't seem to narrow down the misconfiguration in my network-scripts. I'm not that familiar with mixing IPv4 and IPv6, with the WiFi and Windows setup's working I don't believe this is a router misconfiguration either.

Most other forums have notes about adding routes, but they don't typically describe what I'm seeing below, prior to suggesting adding a route.
Code:

192.168.100.0   0.0.0.0         255.255.255.0   U     100    0        0 enp3s0

returns successful from the router

Any help would be great

D-Link DSR-150 Router had a VLan option set up. Disabled that, works fine.

Thanks for providing solution. I was looking at your problem this morning and everything was fine with your setup, so I got curious ...
