Livingston IRX 211 Router

Routing with the Livingston IRX 211 for Leased Line

Packet Filtering

Rules Syntax
Command Syntax
Filter Builder

To install packet filters on the Livingston IRX-211, you need to create two filters with the add filter command. For example:

add filter s1.in
add filter s1.out

After you create the filter sets you must then add the rules.

Rules Syntax
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM] [ log ]
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM] tcp
		[ src eq\|lt\|gt Tport ] [ dst eq\|lt\|gt Tport ] [ established ] [ log ]
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM] udp
		[ src eq\|lt\|gt Tport ] [ dst eq\|lt\|gt Tport ] [ log ]
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM]
		icmp [ type Itype ] [ log ]

You can generate your own security profile for the Livingston from our Filter Builder.

After you have created a security profile and typed in the input and output filter you can apply them to the serial interface on your router. If your serial interface is s1, use:

set s1 ifilter s1.in
set s1 ofilter s1.out
save all
reset s1

Command Syntax
show	table	filter
show	filter	Filtername
save	filter
add	filter	Filtername
delete	filter	Filtername
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM] [ log ]
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM] tcp
		[ src eq\|lt\|gt Tport ] [ dst eq\|lt\|gt Tport ] [ established ] [ log ]
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM] udp
		[ src eq\|lt\|gt Tport ] [ dst eq\|lt\|gt Tport ] [ log ]
set	filter	Filtername RuleNumber permit\|deny [Ipaddress/NM Ipaddress/NM]
		icmp [ type Itype ] [ log ]
