FreeBSD / D-Link IPSEC problems

No luck in IPSEC between a FreeBSD 5.4 (racoon) and a D-Link DI-804HV 🙁

Tried manual and IKE, SAs up but no traffic through the gif device. Perhaps D-Link could add more troubleshooting functions into their firmware (e.g. show routing table, SAs, disable NAT, routes through PPTP or L2TP tunnels).
