? 3550 InterVlan ACL

[admin_2]

I config two Vlan on Catalyst3550-EMI,

Vlan1 IP Address 10.241.0.1/24

Vlan100 IP Address 10.244.0.1/24

I hope that vlan1 can access vlan100, but vlan100 cann't access vlan1.

Please help me!

Thanks

This type of unidirectional access isn't easy because you need filters that can keep state on connections, which normal ACLs don't. See if the 3550s support Reflexive ACLs -- if not, you may be out of luck.
