I have a CSS configured as a load balancer for multiple VLANs using trunk mode. VIP and server are on VLAN1. Users can access the VIP from VLAN1 (no firewall in this case); users can't access the VIP from VLAN2 (cross firewall). Firewall allows all traffic between two VLANs. Users can access the servers directly. Also load balancer appear to be configured properly as there are other working services (non-firewalled). The firewall is an ASA firewall. What could be the issue?
