Radius-server instead of DHCP-server is used, in this case the fastDPI in conjunction with the fastPCRF serves as a DHCP-server. This operation mode can be briefly described as follows: text/html 2026-04-09T16:05:10+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.vasexperts.com/doku.php?id=dpi:bras_bng:bras_l2_vlan:bras_l2_vlan_dhcp:bras_l2_vlan_dhcp_relay&rev=1775750710&do=diff DHCP relay agent Description This mode is intended for the networks where DHCP servers are used to assign IP addresses. This mode is used to track the beginning/end of user session. It is assumed that DHCP servers are placed within a separate network segment that is not directly accessible to users. FastDPI BRAS serves as a relay agent for DHCP requests from user equipment to DHCP servers and for reverse-direction flow, i.e. for responses from DHCP servers to user equipment. text/html 2026-04-09T16:05:10+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.vasexperts.com/doku.php?id=dpi:bras_bng:bras_l2_vlan:bras_l2_vlan_dhcp:dual_dhcp&rev=1775750710&do=diff DHCP Dual Proxy DHCP Dual Proxy (hereinafter — Dual DHCP) — in this mode, fastDPI operates as a single authorization point, requesting all parameters from the RADIUS server via fastPCRF in a single request. The mode is optimized for Dual Stack (IPv4/IPv6) subscribers, but also fully supports IPv4-only and IPv6-only subscribers.
