We have a scenario to decide on implementation for Xenapp 7.x. Implementation is targeted for only Xenapp with session recording. No VDI is required.
1> User --> Nat Firewall --> Xenapp Storefront.
Incoming user Ips are natted to same class range of Xenapp application servers IPs, NAT done in-between firewall, before request comes to Xenapp storefront. Citrix doesn't even know the actual user Ips, it will receive only NAT Ip, Do we require Netscaler for this environment.
Storefront and Application servers are in same network and rest others master servers in other network.
