It makes you look lame :-) */ | | |I have asked the list before about this routing problem but apparently |didn't give enough info for you folks to understand the situation. So here |goes again. (Sorry it's so wordy.) | |I have a box (kernel 2.2.14) setup to provide a single line ppp dial-up to |make connection to our campus network. (So I can connect to the campus net |from home without going thru an ISP) It worked very well until I installed |IP Masq. With IP Masq it routes to/from everything on the internet OK but |does not route to the campus subnet that the linux box is on. (I can no |longer ping the subnet the box is on but I can still ping everything else.) | I assume there must be a very simple answer as to why this happens. | |The box has two NIC's and a modem: |eth0 interfaces to the campus net with a static IP (134.139.180.73) |eth1 interfaces to a local private net (192.168.0.x) |The modem accepts incoming ppp. | | --------- | | | | | || | | <--> [dial-up ppp line] |[campus network] <--> linux box || | | | <--> [private network] | --------- | |With IP Masq all the machines on the private net (192.168.0.x) can see |everything on the campus net and beyond, no problem. | |Here is what I have in my rc.firewall: |#!/bin/sh |# |/sbin/depmod -a |/sbin/modprobe ip_masq_ftp |/sbin/modprobe ip_masq_raudio |/sbin/ipchains -M -S 7200 10 160 |/sbin/ipchains -P forward DENY |/sbin/ipchains -A forward -s 192.168.0.0/24 -j MASQ |# | |My routing table looks like this: |Destination Gateway Genmask Flags Metric Ref | Use Iface |192.168.0.10 * 255.255.255.255 UH 0 0 | 0 ppp0 |192.168.0.0 * 255.255.255.0 U 0 0 | 0 eth1 |134.139.180.0 * 255.255.255.0 U 0 0 | 0 eth0 |loopback * 255.0.0.0 U 0 0 0 lo |default 134.139.180.1 0.0.0.0 UG 1 0 | 0 eth0 | |My options.ttyS1 file has: | 192.168.0.1:192.168.0.10 | |And ifconfig gives: |eth0 Link encap:Ethernet HWaddr 00:A0:24:3B:95:30 | inet addr:134.139.180.73 Bcast:134.139.180.255 |Mask:255.255.255.0 | |eth1 Link encap:Ethernet HWaddr 00:00:C0:77:B0:48 | inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0 | |lo Link encap:Local Loopback | inet addr:127.0.0.1 Mask:255.0.0.0 | |ppp0 Link encap:Point-to-Point Protocol | inet addr:192.168.0.1 P-t-P:192.168.0.10 Mask:255.255.255.255 | |Any help most appreciated. | |Thanks | | Eh, ppp0 has the same address as eth1 !!!! And check out ppp0's netmask... You can put a ppp link on the same subnet, but not on the same IP! -JMS _______________________________________________ Masq maillist - [EMAIL PROTECTED] Admin requests can be handled at http://www.indyramp.com/masq-list/ -- THIS INCLUDES UNSUBSCRIBING! or email to [EMAIL PROTECTED] PLEASE read the HOWTO and search the archives before posting.
