Routing problem (RRAS VPN)

-

have rather confusing issue, been @ couple of hours , i'm getting no where. appreciate input.

virtual machine hosted elsewhere:
machine 1: 192.168.220.20 (rras server)
machine 2: 192.168.220.40

office network:
machine 3: 192.168.100.45 (monitoring server)

vpn setup between 2 networks.

machines 1 , 2 have 2 virtual adapters each. 1 public facing , 1 private network our office via vpn

i'm assured 100% there no block on outgoing traffic virtual servers.

monitoring server (3) monitoring on local subnet , on remote subnet excluding machine 1.

i'm looking why monitoring active checks aren't working on machine 3 we'll @ ping.

pinging office machine 3 machine 2 - using wireshark can see packets leave machine 2, hit machine 1 , vanish down private network - next trace @ office fw, works fine.

when pinging machine 3 machine 1 packet sent on public adapter , recieves message host not found (obviously 192.168.100.45 isn't going found on internet)

have static route setup on machine 2 (192.168.220.40) so:
persistent routes:
code:
 network address     netmask gateway address metric    192.168.100.0  255.255.255.0  192.168.220.20    1

i assume machine 1 being rras server (it setup before joined company) doesn't need persistent route adding rras setup have taken care of it. i'm afraid of adding in persistant route above manage server via rdp. don't want traffic stop!

i've added persistent route machine 1:
route add 192.168.100.45 mask 255.255.255.255 192.168.220.20 metric 1 if 0x10005

0x10005 private network adapter.

seems stops traffic destined machine 3 entire .220 subnet.

question is, heck have missed routing traffic machine 1 destined .100 subnet via public adapter?

appreciated,

thanks.

hi axide,

 

thanks posting here.

 

can show route table form machine1 acted internet or vpn gateway server machine 2 hosed on virtual machine.

machine1 should has dedicate interface vpn tunnel subnet 192.168.100.0 ,could show “ipconfig /all” result ?

 

please first remove persistent route entry added ，perform “tracert 192.168.100.45” , post result here.

 

machine3---(192.168.100.0)----firewall-------vpn/internet--------machine1----(192.168.220.0)----machine2

 

thanks.
