If your IPsec gateway is the default gateway for the range of IP's you
are handing out for L2TP, then ensure you have the proper NAT rules in
place. If the IPsec gateway is not the default gateway, life becomes
pretty complicated, and you're best bet is to NAT all ips to the IPsec
gateway's public IP (excluding NAT for the local networks of course)
