Hi Vitaly, a guess would be a problem with your certificates. You could try to replace the CA based solution by localy stored certificates: remove all left/rightid and -rsasigkey and add left/rightcert conn %default type=tunnel keyingtries=1 keyexchange=ike ikelifetime=240m keylife=20m # leftrsasigkey=%cert leftcert=leftgatway.cer left=%defaultroute leftupdown=/etc/ipsec.updown # leftid=@left.gateway.fqdn.name # rightrsasigkey=%cert pfs=yes compress=yes auth=esp authby=rsasig # sample connection conn sample right=x.y.z.149 rightsubnet=10.0.0.0/24 # rightid=@right.gateway.fqdn.name rightcert=right.cer # Right security gateway and subnet behind it. auto=start Then store the certificates in the /etc/ipsec.d directory and try again. In case this works you could review your CA structure. A good paper ist http://www.twi.ch/~sna/strongsec/freeswan/install.htm otherwise you could try to go back to preshared secrets discribed in the freeswan dokumentation to verify basic functionality of your VPN. hope this helps, Thomas Vitaly Shishakov wrote:

Dear all. i need to establish an IPsec tunnel between two networks. both gateways use FW2. i did everything like it is described in http://www.nadmm.com/show.php?story=articles/vpn.inc (in respect to my case, of cource) but i get the following errors:

below is sample of one of mine ipsec.conf. (updown script borrowed from a link in the above article)
