First of all, thanks to RedHat there is now confusion about ipsec.conf.
Openswan (and freeswan in the old days) used "ipsec.conf" for its
configuration. RedHat, when using ipsec-tools, which uses racoon and
setkey, decicded to call their setkey script 'ipsec.conf'.

So, in short. You're asking the wrong people here, since this is the
Openswan list, and we are not Racoon/setkey experts.

This could be path mtu problems, which happens on NETKEY kernels.

MTU problems.
