Edgemax OS VPN, to Barracuda Link Balancer

Posted on 2016-09-10
Medium Priority
Last Modified: 2016-11-02

I really need help on this one, I have an EdgeMax Lite with IPEC going to a Barracuda 430 LB with again IPSEC and for the life if me I can not get the too to connect. My last attempts is below:


Local IP ANY

Encrypt 3DES

Hash MD5

DH Group 1

Pre-Share Key  *******



ESP-GROUP Lifetime is 3600 no compression, tunnel, PFS enabled 3des

IKE-GROUP Lifetime is 14400 ikev2-reauth no, key-exchange ikev1, mode none, DH-GROUP 2, 3des, md5

Below is what I am getting from the the Barracuda Link Balancer:

2016-09-10 13:50:56
"EDGEMAX-" #274: initiating Main Mode
2016-09-10 13:50:56

2016-09-10 13:45:04

2016-09-10 13:44:43

2016-09-10 13:43:54
"EDGEMAX-" #272: initiating Main Mode

I have tried AES, SHA1, DES etc etc etc and nothing seems to do the trick, I tripple check each side to make sure they match (which they do) so I am at a loss on this?

Any help would be appreciated!

basically, the both sides should have the SAME or similar configuration for the VPN channel to be established. can you also provide the configuration of the other end?

one thing was noticed in my quick review: NAT Traversal.

is any of the two VPN gateways behind another NAT firewall?

another thing is "left=%any" at EDGEMAX side, why is it set to "any" instead of a specific address of the remote peer?

Thanks! The only NAT is at the firewalls themselves, so no NAT needed there, I changed the "left=%any" to "left-" remote firewall IP, changed the IP on the PEER settings on the EDGEMAX, has those backwards I believe:

Site-to-site peers

Remote  Peer
Description PRSDNJ
Local IP
Pre-shared secret
Local subnet (BARRACUDA) internal
Remote subnet (EDEMAX) internal

it looks like the EDGEMAX side always retries duo to no response from the peer. does the Barracuda side work well with sites , if any? is the IP of Barracuda side load balanced?

Yes the Barracuda is working fine with IPSEC against 2 Cisco VPN Small Business Devices no problems, as for the barracuda, its only using 1 link out , so no balancing going on, our IPS is comcast metro ethernet  500mb up/down
