Can you add the pfSense config and the pfSense ipsec logs too? Just use placeholders for secrets/public IPs and so on for posting here.

Update - I noticed that in the PIX when using the "isakmp key ***** address 0.0.0.0 netmask 0.0.0.0" it used the defaultRAGroup–-> I removed the pre shared key from that group and added it to the dafaultl2lGroup and on the PIX is looks like phase 1 is getting further....

but this is the config and log from pfsense which still indicates phase1 is failing.

Got it !

On the PIX side I needed "isakmp identity auto"
