I'm very much out of ideas here: I run mobile IPv6 on Ubuntu oneiric, with a simple fixed-address setup.
mip6d establishes a tunnel, but as soon as the tunnel establishes I lose all network connectivity. I cannot ping, I cannot telnet/ssh, existing connections die, and even ping6 ::1 gives "Operation not permitted". I also have other network interfaces and I lose network on those as well.
There is no Firewall, no ip6tables rules that deny or drop anything, ufw is disabled, and I am running as root.
If I misconfigure MIPv6 so that it fails to establish the tunnel, this doesn't happen and I can ping and everything.
Home agent is 2001:db8:aaaa::4 Mobile node is 2001:db8:aaaa::2
As soon as I kill mip6d I can ping again, both external stuff and ::1, but I can't for the life of me understand why I lose everything when the tunnel is up, even on other network interfaces.
This issue is really a big problem for me right now and I appreciate any helpful pointers or hints.
mip6d is v2.0.2-umip-0.4
This is my home agent config:
#mip6d.conf : A basic Home Agent example
NodeConfig HA;
DebugLevel 10;
DoRouteOptimizationCN disabled;
Interface "eth1";
UseMnHaIPsec disabled;
IPsecPolicySet {
HomeAgentAddress 2001:db8:aaaa::4;
HomeAddress 2001:db8:aaaa::2/64;
IPsecPolicy HomeRegBinding UseESP;
IPsecPolicy TunnelMh UseESP;
}
This is my mobile node:
# mip6d.conf : A basic Mobile Node example
NodeConfig MN;
DebugLevel 10;
DoRouteOptimizationCN enabled;
Interface "eth1";
UseMnHaIPsec disabled;
DoRouteOptimizationMN enabled;
UseCnBuAck enabled;
MnHomeLink "eth1" {
HomeAgentAddress 2001:db8:aaaa::4;
HomeAddress 2001:db8:aaaa::2/64;
}
This is the log output of mip6d on the mobile node:
