Re: win95/netscape/smartupdate over ipmasq failure
I am replying to my own thread since I found the problem.
It turned out that I had my mtu/mru setting different for my eth0 and
ppp0 network devices. This apparently can cause problems since I had
the ppp0 set at 552 and eth0 at 1500. And since ip packet defrag is on
in the kernel for IP_MASQUERADE support then the ppp0 device was
refusing to defrag the large packets fromt the internal network. I
guess no one knows who to blame for this but it is a known problem but
not well documented.
Bottom Line: Make sure and have your mtu/mru settings the same on all
devices involved with ip masqurading.
I hope someone else can benifit from this.
