Simultaneous Basic NAT and NAPT
Simultaneous Basic NAT and NAPT (or PAT) are supported. In this mode, the
servers (private IP addresses) using Basic NAT are configured and the devices
(private IP addresses) using NAPT are optionally configured (static mappings). If
not configured, the remaining private IP addresses default to NAPT.
Enabling Basic NAT does not disable NAPT. When both Basic NAT and NAPT are
enabled, Proxy ARP can also be enabled, although it is only used for Basic NAT.
IP Options Processing
Basic NAT and NAPT functions handle and process the IP datagrams, with options
set as described below. No command is available to set IP options.
The router does not process (and drops) any IP datagrams with the following IP
options:
„
Loose source and record route (type 131)
„
Strict source and record route (type 133)
„
Security (type 130)
„
Stream ID (type 136)
The router does process IP datagrams with the following IP options, but does not
provide its IP address or timestamp information in the response message:
„
Record route (type 7)
„
Timestamp (type 68)
