Guest Traffic

melwin.uk · ‎03-27-2010

Hello Netpro

I want to isolate Guest user traffic from LAN traffic and allow them internet only. All internet browsing traffic is through Microsoft ISA Server.

Guest can connect using Wireless Access Point which is also shared with Data Network.

Microsoft ISA Server is in server vlan? How to isolate Guest traffic?

The simple answer is to setup a Guest VLAN.

Hello

creating guest vlan is ok, but how do I restrict traffic communicating with other vlan on L3.

I did test by aplying ACL but doesnt seems to work.

Hi,

Can you share the ACL that you applied to Guest traffic?

Do you have a firewall in your network that you can use for securing traffic?

guests: vlan 99 (192.168.25.0)
server: vlan 5 (192.168.1.0)
user : vlan 6 ( 10.10.10.0)
dns/dhcp: 192.168.1.111
proxy: 192.168.1.99:8080

ip access-group Guests_in in

Inbound ACL

ip access-list extended Guests_in
permit tcp 192.168.25.0 0.0.0.255 host 192.168.1.99 eq 8080
permit udp 192.168.25.0 0.0.0.255 host 192.168.1.99 eq domain
permit udp any any eq bootps

ip access-group Guests_out out

Outbound ACL
ip access-list extended Guests_out
permit ip host 192.168.1.99 192.168.25.0 0.0.0.255
permit ip host 192.168.1.99 any

Hi - did you solve this? I have a very similar problem - guests are assigned to a VLAN correctly, but the ACLs don't seem to apply to them?

Hi,

Make sure you have associated the correct vlan (#switchport access vlan guests) to port to which the wireless access pint (WAP) or a Guest PC is connected.

Please rate the helpfull posts.

access-list 101 deny ip 10.0.10.0 0.0.0.255 10.0.11.0 0.0.0.255

access-list 101 permit ip 10.0.10.0 0.0.0.255 any

access-list 101 permit ip 10.0.12.0 0.0.0.255 any

access-list 110 deny ip 10.0.12.0 0.0.0.255 10.0.10.0 0.0.0.255 log
