I am unable to connect anyconnect to Flex VPN server.
I am getting IKEv2-ERROR:: Packet is a retransmission for a few tries debug information
eventually “failed to receive the AUTH msg before timer expired”?
I just wanted to confirm all evidence is pointing towards that it’s a NAT issue?(blocked ports)
My ISP router is being used as the WAN interface I have a static public IP address on the iSP router. Port for IPSec/VPN has been forwarded to the Cisco routers interface.
any help or alternatives would be much appreciated.
Go to Solution.
Update: This was a version error, using wrong version of anyconnect, this has now been resolved.
this is due to 4.9 a lot of hash/cryptography where removed!
currently using 4.8, seems to have solved all issues.
