Routing Problem - VPN

Hello all.
A few years ago it used to untangle and am very pleased with this fantastic platform.
Some months I've been problems to make a routing to VPN.
I'll try to explain with diagrams to try help me:

I need to go through the "my computer 1" to "my computer 3".

Now i can:

My computer 3 - Can ping all network !
My computer 2 - Can ping all network !
My computer 1 - can ping "my computer2"
can ping 10.68.89.254


Now the problem:
In untangle machine 10.68.88.253 put the route:
10.0.10.0
mask 255.255.255.0
gateway 10.68.89.254

but when I do a tracert the package does not come for VPn but to the router's web..

untangle why that is not doing the route?
Thanks for your help!
