But this line shows up only with PSK, not with X.509 certificates. Could it be 
a routing problem as well?

If there is anyone with a working IPsec NAT-T (NAT on both sides) 
configuration with X.509 certificates, please be so kind as to post your 
configuration files. Maybe my problem is just a small misconfiguration as 
Jacco suggested.
