>> SLB port 1# /cfg/slb/port 2
>> SLB port 2# add 11
>> SLB port 2# filt enable
>> SLB port 2# apply
>> SLB port 2# save
Notes
• Within each filter, the smask and dmask values are identical.
• All parameters for both filters are identical except for the NAT direction. For Filter 10, nat
source is used. For Filter 11, nat dest is used.
• Filters for static (non-proxy) NAT should take precedence over dynamic NAT filters (see
NAT, page 386). Static filters should be given lower filter numbers.
• After port filtering is enabled or disabled and you apply the change, session entries are deleted
immediately.
