FlashProxy Shared ISP Adds SOCKS5 UDP ASSOCIATE Support

FlashProxy has added support for the SOCKS5 UDP ASSOCIATE command to its Shared ISP plan. The capability is live on existing credentials - customers on Shared ISP can route UDP traffic through their current SOCKS5 endpoint without provisioning a separate tunnel or switching protocols.

UDP ASSOCIATE is one of three commands defined in the SOCKS5 specification (RFC 1928), and it tells the proxy to open a relay for connectionless UDP packets rather than the TCP streams SOCKS5 handles by default. Most commercial proxy providers ship only the TCP path, because implementing a UDP relay at scale is operationally harder. For Shared ISP customers, this brings UDP transport into the same plan that already delivers ISP-hosted IP trust at shared-pool pricing - all on credentials that are already provisioned.
