Hi  list,

I have enabled routing in my corporate switch, I had configured a
cisco 2800 from my ISP doing intervlan and I have moved VLANs of
corporation to my switch 3COM 5550G, but actually I have had some
issues putting ACLs, I have got block only traffic for VLAN 40, it
works fine, but for vlan 35 ACL does not run, with ACL 3035 PCs can
not reach any host of my servers (vlan 30) . Can anyone help me with
this configuration, thanks in advance.
