Hi,<br><br>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.
<br>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:<br><br>12:16:46.007191 IP vpn-server > roadwarrior: ESP(spi=0x3b2c8ac1,seq=0x6), length 84
<br>12:16:46.009699 IP vpn-server > roadwarrior: ESP(spi=0x3b2c8ac1,seq=0x7), length 68<br>12:16:46.896071 IP roadwarrior > vpn-server: ESP(spi=0x707a54a7,seq=0x8), length 84<br>12:16:46.898789 arp who-has roadwarrior tell vpn-server
