SVI ACL's with Return Traffic problems

Hi All

I have 3 vlans

10 = User network

20 = Server Network

30 = WAN

I have an ACL on the VLAN 10 SVI OUTBOUND that (denies all traffic except pings from VLAN 20) and (allows all traffic from VLAN 30)

I have an ACL on the VLAN 20 SVI OUTBOUND that (allows HTTP HTTPS and pings from VLAN 10) and no other traffic

When I remove the ACL from SVI VLAN 10 then I can access VLAN 20 properly but also allows then servers in VLAN 20 more access to VLAN 10.

As Soon as the ACL is put back on then users report access problems to the Server VLAN......

Looks like that ACL's are blocking the return traffic in some way....

What am I doing wrong (Head stuck firmly up my own.... ) or are my remote users (techs) lying to me ?
