VLANs, ACLs. Problems with outbound web traffic.

[ssc_2]

Hi All,

I'm currently trying to configure ACLs on inbound traffic to two different routed VLANs. VLAN4 is my Unified Communications VLAN and I have applied all the rules as per config below and everything is working as expected. I.e. incoming traffic hits OCS and outbound traffic (web and to SIP 5061) works. Actually, the only initial problem I had was with outbound web and SIP traffic.. but as soon as I added following ACE that started to work as well:

100 permit tcp 0.0.0.0 255.255.255.255 212.140.38.8 0.0.0.7 gt 1024 established

BUT, here's my problem. I have a second VLAN with proxy servers (VLAN2) and I have created a separate ACL as per below. As soon as I add the ACL to VLAN2 however, outbound access from my Unified Communications VLAN stops working. Everything except outbound traffic from my proxy VLAN works as well but outbound web browsing etc won't work.

Internet gateway is attached to VLAN1. The Switch is a Procurve 3500. Any ideas? Any help appreciated!
