I have two crypto map, one dynamic for my vpn clients and another for vpn site-to-site. The thing is that the vpn site-to-site works perfect until I put authentication for the dynamic vpn. After that, my vpn clients authenticate perfect but my vpn site-to-site won´t pass phase 2. The logs says "ISAKMP Phase 2 retransmission". If I remove the authentication line, in a couple of minutes vpn site-to-site is up again. Any ideas to solve this? Thanks in advance.
The problematic line

Just wonder if you need to disable extended authentication
isakmp key netscreen address aa.bb.cc.dd netmask 255.255.aa.bb no-xauth
