ip config
Show/set global IP stack configuration options.
SYNTAX:
where:
ip config [forwarding = <{off|on}>]
[firewalling = <{off|on}>]
[redirects = <{off|on}>]
[sourcerouting = <{off|on}>]
[netbroadcasts = <{off|on}>]
[ttl = <number{0-255}>]
[fraglimit = <number{1-1024}>]
[defragmode = <{normal|always|nat}>]
[addrcheck = <{off|own|static|dynamic}>]
[mssclamping = <{off|on}>]
forwarding Disable (off) or enable (on) the IP routing functionality. OPTIONAL
firewalling Enable (on) or disable (off) IP firewalling (master switch).
If applicable, the CLI firewall level allows configuration of the
SpeedTouch™ firewall.
The default is on (for security reasons).
Note It is strongly recommended never to disable the
SpeedTouch™ firewall.
OPTIONAL
redirects Disable (off) or enable (on) the sending of ICMP redirect messages.
A router can send a redirect message in case a shorter path than
the path followed is discovered.
The default is off (for security reasons).
OPTIONAL
sourcerouting Disallow (off) or allow (on) IP source routed packets.
IP source routed packets are packets with the route to follow
specified in the header.
The default is off (for security reasons).
OPTIONAL
netbroadcasts Disallow (off) or allow (on) net directed broadcasts.
The default is off.
In case netbroadcasts are allowed, no traces of netbroadcasts are
generated.
OPTIONAL
ttl A number between 0 and 255.
Represents the default Time To Live (TTL) for locally generated IP
packets. This parameter determines the number of hop-counts the
IP packet may pass before it is dropped.
Generally, the time-to-live is 64 hop-counts.
By limiting the time-to-live, continuous circulation of IP packets on
the network without ever reaching a destination is avoided.
OPTIONAL
