Strongswan 5.8.4. Odd issue connecting to a fortigate. The tunnel appears to establish and the SA up. The fortigate shows phase1 and 2 complete but no traffic is passing. The logs on the strongsan show something I'm not used to seeing. It appears somehow that quickmode phase2 is responding on port 500 instead of 4500. But again, it appears to complete. Here the info from the logs. Any ideas?
