Re: ping reply

I forgot:

It is IPSEC tunnel host to net
Ping without tunnel works correctly.

Hallo, I have the following problem: After an upgrade to kernel 2.6.16 from 2.4.32 my connection over tunnel is broken.

I try ping, i doesn't receive reply. The reply packets are lost somewhere in kernel now..

but when I use tcpdump I can see that crypted packet retruns to me. Tcpdump is able to show me decrypted packet ICMP REPLY.

The same problem with TCP connection.
When another host try ping me - I can see ICMP request, no reply, (contrack shows connection as UNREPLIED)


I turns off any firewall, (iptables -L [-t nat] shows nothing)
ip_forward = 1
rp_filter=0
send_redirects = 0
accept_redirects = 0
kernel 2.6.15

Is any way to find out why kernel silently drops icmp packet?
Is anyone who can help me pleaseeeeeeee?
Any idea, any suggestion...
