Re: SRv6 in FreeBSD
Hi Rodney, I haven't said that is not approved or an RFC exist (there are many and some interesting use cases) , but can you tell me of any in production deployments? The conservatory still there, if you check with your customer, how many are willing to deploy it? Open for an offline talk about it as i really like to know if you are seeing other thing..

geo blocking with ipfw ... the easy way
just in case someone wants to do this:
The following script sets up a table (which can be
used for blocking or allowing) in ipfw so that it holds
nets assigned to the USA and Australia.
You may select your own nets of course:
It uses the ipdbtools package.
(I run this from cron)
#!/bin/sh
ALLOWFILE=/root/AU+USA-GEOIPS.ipfw
MAILTABLE=20
ALT_MAILTABLE=21
AU_VAL=1
US_VAL=10200
set -x
#fetch latest geo-ip ranges and set AU and USA into table ${MAILTABLE}
ipdb-update.sh
ipup -t AU=${AU_VAL}:US=${US_VAL} -n ${ALT_MAILTABLE} > ${ALLOWFILE}
ipfw table ${ALT_MAILTABLE} flush
ipfw -q -f ${ALLOWFILE}
ipfw table ${MAILTABLE} swap ${ALT_MAILTABLE}
