[dynamics-user] Mobile node not using port 434

[Srividya T. <sri...@em...>]

Hi,

Is this mailing list active? Please kindly reply. I am using dynamics 0.8.1
version. When the mobile node moves into the foreign network, I noticed that
the tunnel is down and the mobile node is in the request state tunnel forever.
I used tcpdump to see what was happening. I realized that the mobile node
was not using port 434. I checked the mobile node config file, and it has
UDPPort 434.

I have no clue why this is happening. These are few lines from tcpdump on
mobile node. Mobile ip address is 192.168.10.3. Home agent Mobile ip address
is 192.168.10.2. Foreign agent ip address is 192.168.20.2.


00:43:58.193414 192.168.10.3.32769 > 192.168.10.2.mobileip-agent: UDP 46
(DF)
00:43:58.193414 192.168.10.2 > 192.168.10.3: icmp: 192.168.10.2 udp port
mobileip-agent unreachable [tos 0xco]
00:44:44.503414 192.168.10.3.32769 > 192.168.20.2.mobileip-agent: UDP 60
(DF)
00:44:44.503414 192.168.20.2 > 192.168.10.3: icmp: 192.168.20.2 udp port
mobileip-agent unreachable [tos 0xco]

Can someone please tell me what could be the reason and how to fix it.It's
not that mobile node is just using port 32769 everytime.  In a previous run
mobile node used port 32774. Any help would be greatly appreciated.

Thank you.

Vidya
