Hi, everyone:
I am setting two of my home PC's to form a home network, and trying
IP-Masqrading to let them share the Internet access.
My problem is that, Machine A (equipped with a modem) can dial out
and go to the outside world, it can also ping Machine B (no modem
installed). However, machine B can only ping machine A, but never
go to the outside world.
I try tcpdump to check the traffic on machine A, which serves as
gateway of the home network, it shows as follows:
20:04:56.528522 486SLC.li.com > www2.yahoo.com: icmp: echo request
20:04:56.528522 486SLC.li.com > www2.yahoo.com: icmp: echo request
20:04:56.528522 486SLC.li.com > www2.yahoo.com: icmp: echo request
20:04:56.528522 486SLC.li.com > www2.yahoo.com: icmp: echo request
20:04:56.528522 486SLC.li.com > www2.yahoo.com: icmp: echo request
20:04:56.528522 486SLC.li.com > www2.yahoo.com: icmp: echo request
.
.
.
In the above record, 486SCL.li.com is machine B (without modem).
I checked my kernel setting, it says IP-ICMP-Masqrading is "Y",
and IP-ICMP-Masqrading can only be "Y" or "N", not "M".
I also checked /lib/modules/2.0.34-0.6/net/ and found that there is
no file that looks like ICMP.o, and the only file starting with "i"
is ibmtr.o.
Can anyone help me with this?
Thanks a lot!
