Routing issues (?), with Network diagram.

I have been working with this issue I going to tell you about ALL DAY, and right now I am very, very tired of the sentence "Request timed out"!

My network look like the illustration below. Two network 192.168.1.0/24 that is my Home network, and then I have a LabNet where I do labs, and its on its own network, a 10.10.0.0/16. Yes 16! In the LabNet I have one Windows Server 2012 router (RRAS) that can ping ALL computers in the networks, and it have never been any issue. Then we have the member server DC; it can ping ALL computers in LabNet and after a reboot it can evenfor a short time ping hosts in the Home network, Yes, for a short time! Even clients that are on LabNet have this issuem but not the router.

- All firewalls are disabled.
- The Hyper-V 2012R2 server have two Intel Nics (EXPI9301CTBLK with MS drivers), where Wan switch is an "External network", and Internal is a "Internal network".
- The router that connects everything is a Asus RT-N66u with this static route:
Net: 10.10.0.0
Mask: 255.255.0.0
GW: 192.168.1.4
Interface: Lan

This route make it possible for me to ping the LabNet hosts from Home network. Never any issue that way!

- The Windows Server that are a router via RRAS have this static route, is it correct?:
Net: 192.168.1.0
Mask: 255.255.255.0
GW: 192.168.1.1
Interface Wan

- I have Internet access on all machines in the networks. Both in Homenet work and in LabNet.
- If I run a ping -t 10.10.0.10 and a ping -t 192.168.1.25 the DC in LabNet will reply!!!!
- When I do Pathping from DC to 192.168.1.25 it stops at the Windows router. When I do pathping to 192.168.1.1 from DC it will go all the way. And never any issue pining the Asus router.
- No inbound or outbound filters on any interface in RRAS.
- I have tripple-checked the Nic settings".
- I dont find any unusual events in my friend Event viewer.
- No static routes under my userprofile
- I can ping all hosts via the Asus router.

I have reinstalled Hyper-V Server 2012R2, and gone back to snapshots. Still this annoying issue.

This my the routing table in the Asus router.

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 LAN
10.10.0.0       192.168.1.4     255.255.0.0     UG    1      0        0 LAN
default         78.xx.xx.xx     0.0.0.0         UG    0      0        0 WAN

Anyone have any idea what I am doing wrong? :-)
I have read every article on technet about routing and issues like this.

Thanks in advance.
