TFTP connection rejected Port 69 Unreachable

[Daywalker01]

Hi

I am trying to connect to my OXE wia IP Desktop Softphone 11.0.30 but after the weekend it stopped working.
The client is just displaying "CONNECTION LOST"
But all the Physical Phones are working (different subnet and VLAN thought)

I traced the communication with Wireshark but the only communication I got was the Following:
(10.1.1.2 is the OXE)

Code: Select all

99	6.193379000	10.17.195.13	10.1.1.2	TFTP	92	Read Request, File: lanpbx.cfg, Transfer type: octet, blksize\000=1428\000, timeout\000=5\000, tsize\000=0\000
100	6.193430000	10.17.195.13	10.1.1.2	TFTP	92	Read Request, File: lanpbx.cfg, Transfer type: octet, blksize\000=1428\000, timeout\000=5\000, tsize\000=0\000
101	6.193776000	10.1.1.2	10.17.195.13	ICMP	120	Destination unreachable (Port unreachable)
102	6.193778000	10.1.1.2	10.17.195.13	ICMP	120	Destination unreachable (Port unreachable)
145	11.193903000	10.17.195.13	10.1.1.2	TFTP	92	Read Request, File: lanpbx.cfg, Transfer type: octet, blksize\000=1428\000, timeout\000=5\000, tsize\000=0\000
146	11.193944000	10.17.195.13	10.1.1.2	TFTP	92	Read Request, File: lanpbx.cfg, Transfer type: octet, blksize\000=1428\000, timeout\000=5\000, tsize\000=0\000
147	11.194593000	10.1.1.2	10.17.195.13	ICMP	120	Destination unreachable (Port unreachable)
148	11.194595000	10.1.1.2	10.17.195.13	ICMP	120	Destination unreachable (Port unreachable)

Configured as TFTP Servers would be 10.1.1.2 and 10.1.1.3 as backup but communication is just issued to 10.1.1.2
I was looking on the OXE and the Port is definetly open

Code: Select all

> netstat -tulpen | grep :69

udp        0      0 0.0.0.0:69              0.0.0.0:*                           0          10684      -

What am I missing here?
Thank you in advance
