Hello,
our customer has 18 tenants in a building which share a common it infrastructure. Each tenant should be able to access the common resource telephone system and internet. The tenant networks should be separated.
What I did:
a vlan for each tenant with an ip address as a tenant gateway
ipforwarding for all vlans
Is there a possibility to separate the tenant networks, without for each tenant a traffik deny for all other tenants to place?
Switch: X460 G2, FW: 22.3.1.4
Software: NetSight
Thanks in advance
Best Regards

Or use the ACL with ICMP redirect to force the Stream to (for example) a firewall.

Don't forget to implement the return of the Stream !

Thanks pascal for your replay.
I have private vlan "inet" configured
  create private-vlan InetPriv
  configure private-vlan InetPriv add networkv "Inet"
If I then try to add a tenant vlan as "non-isolated"
  configure private-vlan InetPriv add subscriber "ForIB" non-isolated
 I get the error "Subscriber VLAN can not have ip address Configured"
This IP address I need, but nevertheless the routing for this tenant works?

I have solved the problem by having ipforwarding enabled for all vlans and
for each tenant I has created an access list with a mutual exclusion.

This it what I used ... ACLs are very easy with Extreme Networks :)

It's not the case with Cisco ...

Anyway your problem was solved : Great !
