Suppose I have three interfaces: $outside, $inside and $dmz. If I want to block any traffic from $dmz to $inside, unless it is=20 1. Return traffic from $inside to $dmz 2. ICMP traffic in any direction would these rules be sufficient? block in on $dmz pass in on $dmz proto icmp pass out on $inside --=20 Victor Sudakov, VAS4-RIPE, VAS47-RIPN 2:5005/49@fidonet http://vas.tomsk.ru/ --yrj/dFKFPuw6o+aM Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEcBAEBAgAGBQJd1qjxAAoJEA2k8lmbXsY0RCkIALixnsB9NvxFaRAk0QfxBp3V fovMrJZvNJl844FQQJnpoh8u2S524Th7feYLRVDyBeLs4GY7s5AvRdzej5l7fXNn bgtqXt7tHcu76a7pYo/5ry7UOBULjiNqO7v2LcMI3NXNdI6DZc7QemHTFSvqZ3PR N2qeq5PFdJNjycq7Qfn2kUJRncHnYj6vl+BSAXBS26JtFb0waTSKpnm+OPSi+biq lBFrjTdV5aPTHGHlA8TpbzrcgJqGiTHplGZim2BLhy1OVQzNVXJaLvBeA70wdewS 0EVoh8GA+9T4c+bh3fw/5J5uvzuyV7jpjkRnd/+VBuDakd41JKX23kpf40p1W0A= =UKiF -----END PGP SIGNATURE----- --yrj/dFKFPuw6o+aM--
