Question : DNS resolution on PIX firewall

I'm trying to create a L2L VPN, and the only thing stopping me from finishing is:

I need to type a route for the other site's LAN, so I do:

route Outside 10.10.10.0 255.255.255.0 peer.ddns.fqdn

since it asks me for Ip or hostname, however, it doesn't like the fqdn, so i'm thinking i have to enable some DNS feature, but how?

I try:  ping google.com  and it doesn't work either :(

Quick solution? Anyone?

Thanks

even though you see a cisco router in there, commands will be similar
