just upgrade 2 appliances from 2.5 to 3... have 4 in total, they where all connected with ipsec net 2 net.

since the upgrade, it's not working anymore, the 2 with version 2.5 are rock solid.

so , on the version 3, I deleted all configure connection... recreate only 1 between both version 3... and guess what... not working

I have another version 3 ( spare ) so decided to connect it... and create  new connection to 1 of the 'not working' unit... the ipsec connection work for about 10 to 15 min ( guessing ) then it drop dead.. and not able to get it working any more...

I notice on some forum tread that you can modify the config file... but since the result is not working for all , I'm guessing that it still not the root cause.

any one.. any idea ?

on both endian, the connections are connected ( status )

after a while ( 1 hours ) it goes to Close status.

when I check the informations button of the connection, everything look fine.

both green zone are unable to see each other

( remember, in version 2.5, everything was working fine )

so, is it a bug in the upgrade process ?  are the new appliance delivered with version 3 have the same bug ?

what I'm trying to do is IPSec vpn net-to-net connection ( endian to endian ) , the only exemple is on version 2.5, so I guess this has not change.

am I thinking the wrong way here ?

in jira.endian.com (official endian bugtracker), issue #UTM-875

this should be the final fix:
http://share.endian.com/luca/public/efw-ipsec-3.0.52-1.endian9.noarch.rpm
http://share.endian.com/luca/public/jobsengine-3.0.26-1.endian5.i586.rpm
Basically we just removed the leftsourceip since it was needed for a previous ipsec version.

I hope it works, I'll try

Hi mmiat!!

We tried those packages you suggested and they worked just fine!! Which version of Endian Community are you using right now?
Even we tried rebooting both firewalls (they are a lab setup, precisely on purpose before we make an upgrade to all 5 of our Endian firewalls)
I must say, from Endian 2.5 it's a mayor MAYOR upgrade since IKEv2 allows us to specify several SA and simplify IPsec VPN with our customers.

Between our offices we're using openVPN since it already did that. Our business needs are quite particular. From HQ we stablish IPsec with our customers and from our branches we NAT the network so our customer sees us as only one single block of IPs.

I guess right now we could go ahead and use IPsec instead of openVPN...

What would you suggest?

When I get to the office I'll let you know which specific version/build of Endian are we using in the lab.

Thank very much!

Best regards,

LBP

I had many problems with EFW 3.0.5 trying to connect to some Juniper IPSEC.
It was constant drops, and only one segment was connecting. I tried each and every possible config for Strongswan, and no one worked.

In the end what I did was a dirty manual installation of OpenSwan, replacing StrongSwan.
I extracted all files from the Openswan rpm, and manually copy over the 3.0.5. The I replace all startup/stop scripts to match what Openswan needs.
Also I replaced the templates to force the good config for Openswan.
It was ugly, but t works indeed, and Openswan works way better that Strongswan. I have some hiccups from time to time (each N days, or N weeks), but overall works fine.

It seems that they sell us Strongswan as a better package, but in the end it failed miserably.
I can't exactly suggest you anything, I just warn you that Strongswan in Endian 3.0.5 is a POS, it doesn't work for me. After I changed to Openswan it worked from the first attempt.
But I did all manually and with custom files, it can't be replicated easily.
