Also just removed the IPSEC tunnel from both sides and same results.
I see the traffic going to 10.249.16.0/23 (site b) flowing through vtun0 but no reply but when I do a tcpdump -i vtun0 on Site B, I never see the traffic come in at all.
No issues pinging either side of the vtun0 interface using vtun0 interface IPs (10.249.47.0/29)
