I have been using the stock IPsec VPN configuration tool for several years to access my server remotely from my iOS devices. It's just stopped working. Initially I blamed an iOS update (Sorry Apple but your updates are offten a lottery!). Eventually I downgraded strongswan-ipsec and strongswan-libs0 from V5.8.2 to V5.6.0 and it all started working again but I have no idea why.
Anyone got any ideas? Here's the log output:
192.168.xxx.xxx is my local seerver and 86.yyy.yyy.yyy is my public IP
Anyone got any ideas? Here's the log output:
