cisco asa 5505 passing through port 4500 for ipsec server
Hello all and thank you for your time.
I have a barracuda ssl vpn which has the capabilities of creating a IPSEC server. in the documentation for setting it up it states that I must open ports 500 and 4500 in my firewall.
I have a cisco asa 5505 and I have open these ports. I am trying to connect using my android phone but am unsuccessful. when I run a packet trace for port 4500 I receive this
bad-ipsec-natt Bad IPSEC NATT packet This counter will increment when the security appliance
receives a packet on an IPSec connection that has negotiated
NAT-T, but the packet is not addressed to the NAT-T UDP
destination port of 4500 or had an invalid payload length.
Recommendation: Analyze your network traffic to
determine the source of the NAT-T traffic.
port 500 does not appear to have any issuses connecting only port 4500.
can anyone help i'm lost on where to go from here.
