I am getting an errant routing table entry, that I can't seem to prevent. It happens *every* time pump is restarted. I believe what is happening is that my DSL modem/router has DHCP server capability, and it is causing the routing mess. I verified with tcpdump that pump is getting answers from 2 servers. The modem can be set to either bridged or routed. The routed mode has the DHCP capabilites on the LAN port. Right now it is set to bridged, and AFAICT there are no options to turn on/off any DHCP settings when in bridged mode. So I think the modem is misbehaving here and should not be responding to DHCP requests. But in any case, I am thinking ipchains should be effective in stopping this, but so far it doesn't. Configuration: LAN=192.168.10.0 on eth1 WAN=eth0, dynamic IP via DHCP. eth0:0=192.168.10.10 DSL modem=192.168.10.15 The first routing table is 'normal'. The first row is really eth0:0. On the second table, eth0:0 is gone (I guess this is as expected??), and there is a new entry for 192.168.8.0. Ipchains is apparently blocking the IP connection, but still there is something going on.

Is ipchains failing, or something I am missing? -- Hal B [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] -- _______________________________________________ Redhat-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/redhat-list
