I need to create a layer 2 tunnel with a router and a pix 501 and each end. But, if I use IPsec on a the pix501, the throughput is only 5 or so mpbs. Cleartext on a 501 is 60mbps. I can setup a psuedowire on the router, but I don't think the pix 501 supports it? Any ideas? Can I use ipsec with l2tp tunnel, but some how turn off encyrtion to get more throughput?
I have this problem too.
