References: <199908192006.VAA00538@keep.lan.Awfulhak.org> Content-Type: text/plain; charset=koi8-r Content-Transfer-Encoding: 8bit Sender: owner-freebsd-isp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Here is another strangeness but I'm not sure that this is relevant to aliasing. Well, clients are serviced by user ppp on dialin side of server providing dynamic IP distribution per ttyd basis. IPs are real. And everithing is Ok but ICMP (particularly ECHOREQ/ECHOREP). There is normal traffik from clients to Inet and wise a versa on the ppp links. But I can ping and take repley from clients only from ppp host exactly. When I ping them from other hosts I take no repleys. But tcpdump shows that echo-reqs goes from dialup ppp link to the clients PCs. All other proto's works good. There are no FW's rules denying incoming ICMP traffik from clients. Any ideas? -- WBW Andy V.
