We have recently migrated to Exchange 2010 and we are unable to load balance external traffic properly. We are using source IP based sticky, which works fine for all the internal traffic because internal clients have unique IP addresses. All of our external mail traffic comes through a TMG server, which has a unique IP address. The traffic coming from the TMG server is sticking to only one server in the serverfarm. Is there a way to have a vserver use multiple stickies? Thanks, Mohamad

Thanks. I tried that, but according to our exchange administrators, the solution didn't work. Here is my configuration: serverfarm EXCH-CAS nat server no nat client real x.x.248.100 inservice real x.x.248.101 inservice probe EXCH-CAS serverfarm EXCH-CAS-SSL nat server no nat client real x.x.254.60 inservice real x.x.254.61 inservice probe SSL-FARM ! vserver EXCH-CAS virtual x.x.254.154 tcp www vlan 460 serverfarm EXCH-CAS sticky 1440 group 152 replicate csrp sticky replicate csrp connection persistent rebalance inservice ! ! vserver EXCH-CAS-S virtual x.x.214.139 tcp https vlan 400 serverfarm EXCH-CAS-SSL sticky 5 group 252 replicate csrp sticky replicate csrp connection persistent rebalance inservice ! vserver EXCH-CAS-TEST-S virtual x.x.214.139 tcp 0 vlan 400 serverfarm EXCH-CAS sticky 5 group 252 replicate csrp sticky replicate csrp connection persistent rebalance inservice !

Thanks you, Zac. I was thinking about creating two vservers. One that allows only SSL, and the other allows all tcp ports. Both vservers would use the same VIP. When the traffic will come on port 443, the first vserver would be used, and for all other ports, the second vserver will be used.

We are load-balancing SSL successfully but the Exchange people want to use RPC to access mailboxes using CSM. We need to allow ports 6005 through 59530 used by the Client Access Servers. Any suggestions?

I have to implement a VoIP solution for a new facility which will house 150 users. If I use Cisco's solution, what do I need to get. Basically, I am trying to come up with a shopping list to implement Cisco's VoIP solution. Thanks, Mohamad

Where are you using the route maps that you have in City Hall's configuration? Just to confirm -- Is the problem that when City Hall's fails, it can't go out of Library's ISP, correct?

Thanks, Leo. I haven't bought the new chassis yet. I am sure the chassis will clearly be maked as to where the supervisor engines should go. Thanks, Mohamad
