[Olsr-dev] Asymmetric ipip not working
Mon Apr 26 08:43:09 CEST 2010
ok - that's the critical one, and a bug in the olsrd code too. The
olsrd-smartgw-server sets the rp_filter for the olsr interface and for all.
But not for the tunl0 interface. The olsrd-smartgw-client is correct: only
rp_filter on the olsr interface is needed.
Also, ping debugging may give you false positives here: when using NAT on the
outgoing iface, conntrack stores the destination address somehow. Means:
setting rp_filter back to 1 has no effect for an address you pinged recently.
You need an unused ping target to verify the correct ip_filter setup.
