IP redirection : ARP resquest blocked

Hello,

I'm experiencing some problems with IP redirection function with a Aironet 1240AG series.

I would like to provide an access to our network to our registered users.

When the user starts his notebook, he opens a web navigator and types any URL. The IP redirection function must redirect the user to a default web start page. But it doesn't work.

When I analyze the dataflow with Wireshark, it shows me that ARP request are blocked by the AP. When I disable redirection function, the ARP request pass successfully.

In the Cisco datasheet, we can find this :

"The access point does not redirect broadcast, unicast, or multicast BOOTP/DHCP packets received from client devices.

•Existing ACL filters for incoming packets take precedence over IP redirection."

Here are my ACL :

access-list 100 permit tcp any host 157.26.186.22 eq 1723

access-list 100 permit gre any host 157.26.186.22

access-list 100 permit udp any eq bootpc any eq bootps

access-list 100 permit udp any any eq domain

access-list 100 permit icmp any any

access-list 100 permit tcp any host 157.26.186.22 eq www

157.26.186.22 is the IP of the VPN and web server.

What can I do ?

Thanks for your answer.
