Access from host->guest and guest->host

[Yuri Weinstein]

Hello all

I have qemu/kvm running on ubuntu

Two VMs running - ubuntu and Windows
Both NIC setup as bridge network source host device interface/card

Host has IP 192.168.90.5
Ubuntu VM 192.168.90.26
Windows VM 192.168.90.10

All can access external Internet and guest<->guest.
But host->guest and guest->host access does not work.

Can someone point me to the right direction how to make it happen?

Thx in advance!
