16.7 Legacy Series / TFTP blocked

« on: August 15, 2016, 03:15:14 pm »

Hi

I need TFTP for building servers and downloading software internally in our network. Although we have rules that allow UDP/TCP on port 69, the file transfer is blocked:


Aug 15 12:52:50 ny4fw07 filterlog: 175,16777216,,0,ixl2_vlan242,match,pass,in,4,0x0,,64,0,0,DF,17,udp,98,10.132.242.14,10.132.250.203,43011,69,78

I haven't able to find any reference to TFTP in opnsense doc. In pfsense there is a reference that I need a TFTP proxy....

16.7 Legacy Series / Intermittent traffic flow between OPnsense and Cisco ASA VPN

« on: August 12, 2016, 02:48:41 pm »

Hi all

We are trying to introduce OPNsense in our network so we are quite newbie.

We have managed to establish an IPSec VPN between  OPNsense 16.7-amd64 and a cisco ASA5545 running  asa912-smp-k8.bin.

Our problem is the traffic is not crossing the VPN while it is established.

For example, trying to ping a machine in the other end, takes more than 1 minute to respond, but the Ipsec is fully established:


$ ping 10.132.43.117
PING 10.132.43.117 (10.132.43.117) 56(84) bytes of data.
....
64 bytes from 10.132.43.117: icmp_seq=1 ttl=63 time=68.2 ms


From the cisco we see sometimes the below:

Total IKE SA: 5
....
4   IKE Peer: 104.255.200.142
    Type    : L2L             Role    : responder
    Rekey   : no              State   : MM_ACTIVE
5   IKE Peer: 104.255.200.142
    Type    : user            Role    : responder
    Rekey   : no              State   : MM_WAIT_MSG3


From opsense, it doesnt report any problem, as far as I can see. We have increased the logging for "SA Manager", "IKE SA", "IKE Child SA" and still the logs dont show anything noticeable.


Any advice for troubleshooting this problem?

Thanks
