[Openswan Users] Rhel 3 with natt patch?

[Nicole Hähnel]

Hi,

I'm trying to patch the 2.4.21-20.EL rhel 3 kernel with 
openswan-2.1.5.natt.patch. (I can't find CONFIG_IPSEC_NAT_TRAVERSAL in 
.config)

I get this error:

Is there any other patch for a rhel 3 kernel?
Or what is necessary to use nat-t?


Thanks!
