ip forward-protocol udp
<port number>
Use the
ip forward-protocol udp
command to specify the protocols and ports the SROS allows when
forwarding broadcast packets. Use the
no
form of this command to disable a specified protocol or port
from being forwarded.
Default Values
By default, the SROS forwards broadcast packets for all protocols and ports.
Functional Notes
Use this command to configure the SROS to forward UDP packets across the WAN link to allow remote
devices to connect to a UDP service on the other side of the WAN link.
Note
The
ip helper
command must be used in conjunction with the
ip forward-protocol
command to configure the SROS to forward UDP broadcast packets.
Syntax Description
<port number>
Specifies the UDP traffic type (using source port)
The following is the list of UDP port numbers that may be identified using the
text name:
biff (Port 512)
pim-auto-rp (496)
bootps(Port 67)
rip (Port 520)
discard (Port 9)
snmp (Port 161)
dnsix (Port 195)
snmptrap (Port 162)
domain (Port 53)
sunrpc (Port 111)
echo (Port 7)
syslog (Port 514)
isakmp (Port 500)
tacacs (Port 49)
mobileip (Port 434)
talk (Port 517)
nameserver (Port 42)
tftp (Port 69)
netbios-dgm (Port 138)
time (Port 37)
netbios-ns (Port 137)
who (Port 513)
netbios-ss (Port 139)
xdmcp (Port 177)
ntp (Port 123)
Alternately, the
<port number>
may be specified using the following syntax:
<0-65535>. Specifies the port number used by UDP to pass information to upper
layers. All ports below 1024 are considered well-known ports and are controlled
by the Internet Assigned Numbers Authority (IANA). All ports above 1024 are
dynamically assigned ports that include registered ports for vendor-specific
applications.
