A few times a day we experience a stop in the dataflow though our site-to-site VPN, and the below is logged on the Juniper:
2014-03-03 13:26:31 alert IPSec tunnel on interface ethernet0/0 with tunnel ID 0x1 received a packet with a bad SPI. AzureIP->OurIP/144, ESP, SPI 0x1fb5e464, SEQ 0x826.<u5:p></u5:p>
<u5:p></u5:p>After about 5 minutes it starts working again, but by then our terminal server sessions are broken etc, so this is very annoying. Our software version is 6.3.0r16a
When looking at the dashboard, everything seems OK but no traffic is passing. If I disconnect and connect it works again.
We have all our servers in Azure, including DNS so we urgently need a solution. Any help is welcome!
