Which connection method can route internal ICA connections through NetScaler without modifying the existing network routing?

• A. Policy-based Routing
• B. ICA Proxy
• C. SOCKS proxy
• D. Transparent Mode

Answer: (B)

ICA Proxy is the method that lets NetScaler publish internal Citrix resources by handling ICA traffic through the appliance without changing how the internal network is routed. It works by terminating the ICA session at NetScaler and then forwarding the appropriate streams to the internal Delivery Controllers or StoreFront servers using the existing network paths. Because NetScaler is the entry point for the ICA connection, you don’t need to adjust routing tables or add new routes—the internal network can stay as-is while remote users reach the internal farm through NetScaler.

This approach is purpose-built for routing ICA traffic through the gateway, which is why it’s the best fit. Other options aren’t tailored for this exact flow: policy-based routing would involve changing routing decisions in the network, a SOCKS proxy is a generic proxy not optimized for ICA sessions, and Transparent Mode intercepts traffic differently and isn’t the standard mechanism for publishing internal ICA services through NetScaler.
