Access-list doubt with tagged ports and virtual hosts

Hi,

we have a Procurve 3500 Layer 3, and we want to configure an access-list within vlans.

The problem is that we have defined 3 vlans on the same two tagged paravirtual machine (Xen Source) ports and this vlans, must communicate with others vlans.

What we have to do in order to:
enable ssh (22) access from vlan4 to vlan3.
enable smtp (25) access from vlan2 to vlan3.

Re: Access-list doubt with tagged ports and virtual hosts

Hi

For the SSH:

Sw(config)#ip access-list extended SSH
Sw(config-ext-nacl)#permit ip 192.168.4.0 0.0.0.255 192.168.3.0 0.0.0.255 eq 22
Sw(config-ext-nacl)#deny ip 192.168.2.0 0.0.0.255 192.168.3.0 0.0.0.255 eq 22
Sw(config-ext-nacl)#permit ip any any
Sw(config)#vlan 3 ip access-group SSH in


For the SMTP:

Sw(config)#ip access-list extended SMTP
Sw(config-ext-nacl)#permit ip 192.168.2.0 0.0.0.255 192.168.3.0 0.0.0.255 eq 22
Sw(config-ext-nacl)#deny ip 192.168.4.0 0.0.0.255 192.168.3.0 0.0.0.255 eq 25
Sw(config-ext-nacl)#permit ip any any
Sw(config)#vlan 3 ip access-group SMTP in

Note (please check for any mistakes):
You can permit or deny any other traffic based on your security requirements then you can apply the ACLs.

Good Luck !!!
