New Revision: 197687
URL: http://svn.freebsd.org/changeset/base/197687
Log:
The flow-table associates TCP/UDP flows and IP destinations with
specific routes. When the routing table changes, for example,
when a new route with a more specific prefix is inserted into the
routing table, the flow-table is not updated to reflect that change.
As such existing connections cannot take advantage of the new path.
In some cases the path is broken. This patch will update the affected
flow-table entries when a more specific route is added. The route
entry is properly marked when a route is deleted from the table.
In this case, when the flow-table performs a search, the stale
entry is updated automatically. Therefore this patch is not
necessary for route deletion.
Hi,
Will this fix the issue that I see visualising its self as packet loss
over a VPN tunnel?
The tunnel is an openvpn (tun mode) tunnel providing a route to
192.168.201.0/24 however when I ping an address in this network with
flowtable enabled I see 2-3 out of every 5-6 packets end up being sent
out of bge0 (IP 172.17.XX.XX/23 GW 172.17.XX.1) to the default gateway
(which responds with destination host unreachable) rather than down tun0.
Thanks
Tom
