So I have setup a PPP Profile with a filter incoming rule going to ppp.in and a outgoing filter going to ppp.out. I have a jump in the forward chain going to ppp. I cannot place a rule in the input chain to jump to ppp since it causes an error saying that I cannot match outinterface on the input and prerouting chains.
I was advised by Maris to add a jump from input directly to ppp.in … the problem is that this bypasses the interface checks that ppp does. What is the proper way to run the input through the ppp.in chain?
What is the proper jump? Thanks.
My goal is to pass all of the PPP input and output through filters on both the input and forward chains. Thoughts? Thanks.
