Hi,
<div><br></div><div>We are using openswan-2.6.24rc4 on our ubicom32 IP7K openwrt router. We are doing some site-to-site tests with a different brand router.On our router, we turned on some extra ciphers like blowfish and twofish besides the aes, des, 3des. If we want to use twofish, we are getting the below error on our router.</div>
