Does anybody know (max) supported key size for certificates/keys to use VPN?
I tried (1.3b2) certificates/keys with size 1024 bit and 2048 bit.
They worked. At least vpn started and ping to remote site worked.
certificate/key with size 3072 bit and 4096 bit did not work.
Even channel did not go up.
It was strange that firewall (monowall) started to drop UDP packets:
ipmon: 13:52:34.099331 ng0 @0:21 b 84.xx.30.xx -> 213.xx.251.xx PR udp
len 20 (756) (frag 1260:736@744+) IN
I also tried to check:
"Allow fragmented IPsec packets"
but it did not change the behaviour.
Any comments. Is the limit 2048 bit keys/certificates OR there is anything I
