It is supposed to look like that.

You are breaking the inbuilt security of ipsec. IPsec was designed to NOT
leak out clear text packets when for some reason, encryption would fail.
How do you describe the security of your link now anyway? Is it save for
windows users to logon? Is FTP/pop safe? Your answer now seems to me "most
of the time", which from a security point of view means it only takes
time before security is compromised.
