Hi all,
I’m having some trouble with leap 15.6 and NAT. I used a very basic setup and set:
net.ipv4.conf.all.forwarding=1
net.ipv4.conf.all.rp_filter=0
Then I added:
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
And it works. The problem is the speed because all I get is something around 70kb/s. If I download the very same thing with SUSE directly (wget or curl) it goes beyond 20mb/s so that’s fine. Obviously I’m missing some NAT related settings.
I tried a few more iptables rules I found on the internet but none made a difference. I also found some articles about system settings like net.core.rmem_max. Setting these to higher values didn’t help either and so I’m stuck now.
Any help would be appreciated!
