LD Real Servers cannot acccess internet

[admin_2]

Recently, i have configured Cisco LocalDirector (LD) 430 and 3 web servers in vlan 4 are connected to it. The LD outside int is also connect to vlan4. The LD inside int is connected to vlan 1. The problem is, previously from the web server, using IE, I can go directly to internet without going thru proxy. Now it can't. The backend applications are not able to run because of this as it needs direct internet access.

All my 3 webservers previous and current network config is :

Previous : 172.16.23.x 255.255.255.128. The gateway is 172.16.23.130 our ISP's Load Balancer.

Now : 172.16.23.x 255.255.255.0. the gateway is 172.16.23.10 which is our ISP's router.

Our ISP engineer says it's my LD setting is at fault. Can this be the switch fault? My LD inside n outside interface and all 3 web servers are connected to the same Cisco switch 2900XL.

You can try using the bypass feature. This way all the traffic that needs to go to the internet directly need not pass through the proxy.

Can you supply the LD configuration?

Unless there is something in the LD configuration causing the LD to arp for one of the addresses (server or gateway), there is no way LD is going to prevent a host on the vlan from reaching another host (or gateway) on that vlan.

Thanks

Is your ISP blocking outbound traffic by default? Looks like you widen your subnet mask. Did your ISP make all appropriate changes on the firewall or changes to routes on L3 devices?
