[j-nsp] srx advice

[Richard Zheng]

Hi,

I am trying to compare different models of srx. The application is to setup
virtual firewalls for several customers. The virtual router instance should
do it. The maximum number of security zones seems to be the limitation of
srx. For example, SRX220 has maximum 24 zones and 15 virtual routers.
Considering one virtual router needs at least 2 zones, one trusted and one
untrusted, how can you get more than 12 virtual routers with 24 zones?

Am I missing something here?

Thanks,
Richard
