Cisco ASA: SSL VPN - Backup Connection
I gave up fighting with setting up client profiles on the ASA. Eventually able to adjust the existing preferences file on workstation to successfully configure a secondary connection that would be used if the primary was down--without any additional user actions.

Notepad++ Home: Notepad++
I've used Textpad for years but it costs $. Notepad++ supports regular expressions and looks pretty good. I may make it my new default text editor.

IPv6
IPv6 - Quick Notes
- 128 bit address
- repeating 0's are abbreviated
fd59:8f91:f52d::1:0:0:1 ->
fd59:8f91:f52d:0000:0001:0000:0000:0001
- Loopback - ::1/128
- Link-local - fe80::/10 - can communicate with other machines on same switch
- could end up with interfaces that have the same address
- resolved using scope id
- Scope ID
- only non-global IP's
- only valid on same machine -- don't put on wire.
- postfixed with %
- e.g. http://[fe80::1:2%2]:80/index.html
for interface "2"
- Site-local - fec0::/10
- (like 192.168.0.0/16)
- not officially usable - use unique-local instead
- Useful for lab
- unique-local - fc00::/8, fd00::/8
- fc00::/8 - from allocation authoritiy
- fd00::/8 - randomly assigned via rfc4193
- block these numbers - do not route
- Global - 2000::/3
- All publicly accessible IP's
- No NAT
- Tunnel IPV6 over IPV4
- 6to4 requires endpoint have public IP
- 2002::/16
- Teredo - encapsulate ipv6 packet in IPv4 UDP
- 2001::/16
- IPv4 Mapped - ::ffff/96
- ::ffff:10.67.12.12
- Dual stack (have both)
- security! - will firewall rules apply? tunneling will bypass firewall?
- 128 bit address
- repeating 0's are abbreviated
