I have a suse 7.1 box set up as my router so that I can access the internet from other PC's on my network. Some websites (www.realnetworks.com, www.bahn.de, www.autoscout24.de to name but a few) are not available from masqueraded machines, whereas others are accessible. The problematic sites, however, ARE accessible from the linux machine itself.
Doing a traceroute reveals that the packets are getting most of the way, they just get lost at some routers (I think). [...]
Since installing the linux machine as the router, I have tried a setting the MTU and MRU to 1492 but this
You put them in the options?
made no difference. Interestingly, after setting them, I STILL get the following errors in the syslog when connecting...
pppd: Couldn't increase MTU to 1500 pppd: Couldn't increase MRU to 1500
though checking using ifconfig, the MTU *is* set correctly on both eth1(dsl connex) and ppp0 so I dont think it is an MTU issue. I also tried reducing the MTU further (to 1300) but with no affect.
You do not have to set the mtu with ifonfig, go back to 1500. You have to edit the ppoe-options-file (I now do not know how it is named) and teher have to be the lines mtu=1492 mru=1492 Does it work after restart of ppoed? Rene
