Hi All,
I'm having a bit of a problem with an ikev2 vpn between a cisco ASA (9.5(1)) and the Microsoft Azure platform.
I've managed to get the VPN to establish and pass traffic.
The problem is that intermittently the ASA appears to stop passing traffic (No TX when looking at the Tunnel session details) although the RX seems to increment fine.
If I reboot the ASA it fixes the problem, until the next time which was circa 1 week under little traffic but now a lot more traffic is being copied across the VPN it seems to last a matter of hours.
The SA lifetime is set at 8 hours, with unlimited traffic volume set in the crypto map..
I have a feeling it's something to do with stale SPI's (although not certain).
I would appreciate any help with this, in terms of being certain of what the issue is, or if it's a known issue.
Thanks in advance!
