TOPIC: Racoon is using physical interface rather than logical one

Racoon is using physical interface rather than logical one 8 years 7 months ago #25933

Hi,
I have a situation wherein the machine which I am using has
one ethernet card & I have configured two ips on it
eth0 a.b.c.d physical interface
eth0:1 a.b.c.e logical interface
Now, I want to setup ipsec between logical interface eth0:1 and another host a.b.c.f .
The problem is my machine receives isakmp(racoon) messages on logical interface correctly but is sending back isakmp(racoon) messages through physical interface. I am unable to understand the anamoly. Can anybody explain the behaviour?

Regards,
Raj

universalCitizen,

Obviously your machine is using eth0 as the the source IP address, when in fact you require it to be eth0:1. This is your problem.

I'd suggest you google around using keywords such as ISAKMP, 'the ipsec service your using', and 'source ip address' and you should get some results back. In needed, try any forums that are associated with the IPSec implementation/package your using to see how you can overcome this issue.

Hope that helps.
