Found on palo alto we can't config seconds 86400 (max value allowed was 65xxx). Have to use 1 day but my P1 still wasn't coming up. Changed to seconds and dropped to 28800 on both sides and VPN came up


3600 - 1 hr

28800 - 8 hr

43200 - 12 hr

86400 - 24 hr

config trunk in VMware

 Identify VMNICs 

VMware names them as they boot up so not always in the order you might thing.

Easiest way is plug in the port and watch the VMware interface to see if it shows as up.

Also a good idea to enable CDP on the VMware and the switch on the other side.


We  want to run at least 2 high bandwidth (10gig plus) cables from switch to VMwrae.

Config as trunk on switch


VCenter config

Network virtual siwtches

Go to VMhost

Configurte

Virtual switches 

Add networking

Virtual machine port or for standard switch

select vswitch

Give a name DMZ

Fill in vlan number

Finish


VLAN modes

vlan - pick 250

vlan trunking - pass the trunk onto the VM (won't use it often)

Private vlan - for Pvlans (won't use often either(

punycode phishing

 https://en.wikipedia.org/wiki/Punycode


Scammers using non English characters to make phishing URLs look more legit, some are harder to spot than others.


Urls will have a xn-- in them, some plantforms auto block, some will render the real URL and some will show the punycode which can trick users into clicking it.

You get prompted twice for GlobalProtect with MFA/2FA on palo alto firewall

The usual fix is to put

portal auth > AD 

gateway auth > MFA server


However we found with some OTP/fob code users it wasn't working well


Fix was 

Upgrade GP to preferred release (6.2.3 a time of writing)

Enable the authentication cookie settings on GP


Portal - Generate cookie for auth override

Choose the same cert you use for the GP 


Gateway - Accept cookie for auth override

Choose the same cert you used in portal


Push policy

Watch out for any AD changes may take 15 mins to update on the palo so if you move a user into another group for testing it might not work for 15 minutes
