Hi,
you need to create a static route on your upstream router for the server VLAN with next-hop the ACE.
In you case it will be something like this:
ip route 172.16.34.0 255.255.255.0 "ACE IP address of VLAN34"
In case you have fault tolerance configured, use the alias IP of the ACEs on VLAN34.
Don't forget that your ACL on the ACE needs to allow this traffic.
If you use permit any any it shouldn't be a problem.
HTH,
Dario
