[Openswan Users] l2tpd does not finish pppd connection

[Rafael Andara]

Hi,

I was able to setup a lab vpn server with IPsec/l2tpd without any problem,
but when I put it on production my connection suddenly dies after a minute
or so, I was able to see that pppd was sending LCP EchoReq but it wasn't
getting any response.
I stoped testing and 2 days after it's worse the connection isn't
established, the chap challenge doesn't get to client and I see this with
tcpdump:

12:16:46.007191 IP vpn-server > roadwarrior: ESP(spi=0x3b2c8ac1,seq=0x6),
length 84
12:16:46.009699 IP vpn-server > roadwarrior: ESP(spi=0x3b2c8ac1,seq=0x7),
length 68
12:16:46.896071 IP roadwarrior > vpn-server: ESP(spi=0x707a54a7,seq=0x8),
length 84
12:16:46.898789 arp who-has roadwarrior tell vpn-server
12:16:47.898825 arp who-has roadwarrior tell vpn-server
12:16:48.898892 arp who-has roadwarrior tell vpn-server
12:16:49.902972 arp who-has roadwarrior tell vpn-server
12:16:50.903013 arp who-has roadwarrior tell vpn-server
12:16:51.903077 arp who-has roadwarrior tell vpn-server
12:16:52.907159 arp who-has roadwarrior tell vpn-server

VPN-server is a NAT server also, with iptables.

any clue???

I hope you can help me
