What you want is local switching of layer 2, but I don't think there is support for frame-relay to ethernet switching. Your other possibility would be PPP half-bridge but not sure if you can do PPP half-bridge over a frame relay connection or not. Wouldn't it be simpler to add a serial interface to the internal router/firewall? - -- ========= bep -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHVHVyE1XcgMgrtyYRAvR2AKDOoyzX37FKuafDBwFFE8gMV/K2igCfS4iI uDBewgyVXQCTDqkTJmqE0es= =IKmJ -----END PGP SIGNATURE----- _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
