Routing Problems on own Server Load Balncing Rule

Question

Hi, we got an Interface (VLAN 253 / 10.0.253.10) and a few server in this VLAN, e.g. 10.0.253.11. The default gateway of all Servers in VLAN 253 are set to 10.0.253.10 and for testing i created these firewall rules : any-any-253 & 253-any-any The IP from the UTM is 10.0.189.151 and the default Gateway 10.0.189.1 
 
 Also we set a few Server Load Balancing Rule like email2016.domain.de ( Additional Address 10.0.189.116 (VLAN 189)) - HTTPS -> EX01 (253.11), EX02 (253.12)... 
 The problem is, I'm not able to open a connection to one Load Balancing Rule from the same Subnet. So email2016.domain.de&#160;(10.0.189.116) works not from 10.0.253.0/24 
 The LB-Rules works per se, like a Server in a nother VLAN. E. g. VLAN 224 / 10.0.224.51 can connect to email2016... without problems 
 Is there a problem in our configuration, or do we have to add a static route?

 hmm, we want to use another server reluctantly. 
 Isn't there a workaround with the utm it selfs, like a static route to our cisco switch's or something?

Maybe with S-NAT-Rules 
 From: VLAN 253 to EX01 change Source to 10.0.253.10 
 The server should send the packets back over the UTM.

Hi CS, 
 thx for this idea. 
 
 An S-Nat Rule works great. 
 VLAN 253 (Network) = 10.0.253.0/24 VLAN 253 (Address) = 10.0.253.10 
 From VLAN 253 (Network) - Service: Any - To VLAN 253 (Network) Change Source To VLAN 265 (Address)
