Hi All,
I just installed a Barracuda Link Balancer 230 last week. I have 2 ISPs and an ASA5500. The LB230 is sitting in front of my ASA5500 and has its Firewall features turned off. All of my services work (OWA,VPN,sharepoint, NATs) with no issues.
For load balancing and failing over when 1 ISP is down this thing is great. I would recommend it for SMBs. it was about $1900 with 3 years of energize from SHI.
My exchange server is NATed to an address on ISP A. The engineer @ barracuda mentioned that i can have my email work even if the link to ISP A is down since we can NAT it to ISP B.
Today i got on the phone with the Barracuda people and had a guy help me configure this. Some NAT rules were created and it looked looked like we set it up so that the link for ISP B would forward email to the address that the WAN port that ISP A is plugged into and then magically get sent to my exchange server as long as i make a change to my A records @ register.com.
While making the changes at register.com it dawned on me that i now have 2 different IP addresses for my mail server. I hate it when i break email so I called register.com to ask some questions and they basically said that this configuration wont work. They said that if i get another cert for email it might work. The Barracuda people didn't mention anything about certs and all they said was make an MX record change and all will work.
I removed all the changes that were made and will look into this a little deeper.
Anyone else using a Barracuda Link Balancer while hosting Exchange?
Anyone have any insight on this product?
Thanks in advance,
Andy
